This commit extends the driver model device's API by function:
- dev_get_driver_ops()
And this function returns the device's driver's operations if given:
- dev pointer, is non-NULL
- dev->driver->ops pointer, is non-NULL
in other case the, the NULL pointer is returned.

This commit extends the driver model uclass's API by function:
- uclass_get_device_by_name()
And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists,
- device probe, doesn't return an error.
The returned device is activated and ready to use.
Note:
This function returns the first device, which name is equal
to the given one. This means, that using this function you must
assume, that the device name is unique in the given uclass's ID
device list.

And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists.
The returned device is not activated - need to be probed before use.
Note:
This function returns the first device, which name is equal

assume, that the device name is unique in the given uclass's ID

This commit introduces simple tests for functions:
- uclass_find_first_device()
- uclass_find_next_device()
- uclass_first_device()
- uclass_next_device()
Tests added by this commit:
- Test: dm_test_uclass_devices_find:
* call uclass_find_first_device(), then check if: (dev != NULL), (ret == 0)
* for the rest devices, call uclass_find_next_device() and do the same check
- Test: dm_test_uclass_devices_get:
* call uclass_first_device(), then check if:
-- (dev != NULL), (ret == 0), device_active()
* for the rest devices, call uclass_next_device() and do the same check

This test introduces new test structure type:dm_test_perdev_uc_pdata.
The structure consists of three int values only. For the test purposes,
three pattern values are defined by enum, starting with TEST_UC_PDATA_INTVAL1.
This commit adds two test cases for uclass platform data:
- Test: dm_test_autobind_uclass_pdata_alloc - this tests if:
* uclass driver sets: .per_device_platdata_auto_alloc_size field
* the devices's: dev->uclass_platdata is non-NULL
- Test: dm_test_autobind_uclass_pdata_valid - this tests:
* if the devices's: dev->uclass_platdata is non-NULL
* the structure of type 'dm_test_perdev_uc_pdata' allocated at address
pointed by dev->uclass_platdata. Each structure field, should be equal
to proper pattern data, starting from .intval1 == TEST_UC_PDATA_INTVAL1.

This commit adds 'uclass_platdata' field to 'struct udevice', which
can be automatically allocated at bind. The allocation size is defined
in 'struct uclass_driver' as 'per_device_platdata_auto_alloc_size'.
New device's flag is added: DM_FLAG_ALLOC_UCLASS_PDATA, which is used
for memory freeing at device unbind method.
As for other udevice's fields, a complementary function is added:
- dev_get_uclass_platdata()

Add gzwrite command to write gzip-compressed images to block devices.
Input must be gzip-compressed according to RFC1952, since the crc
and file size in the trailer will be confirmed during operation.
The decompressed file size must be specified on the command line
for images with decompressed sizes >= 4GiB because the trailer
only contains the low 32 bits of the original file size.

This adds information about the Gateworks System Controller to the gsc command
such as the firmware version, firmware CRC and status of the GSC watchdog
(if its enabled and if its tripped).
Additionally the 'gsc wd' command can be used to enable or disable the
watchdog with the following usage:
gsc wd enable [30|60]
gsc wd disable
Note that the GSC registers are battery-backed by the GSC coincell so once
eanbled, they remain enabled across power-cycles or until either the GSC
firmware has been updated or FLASH has been re-programmed by the Gateworks
JTAG adapter.

The GW551x-A revision does not have the CSI0_DATA_EN pin connected, therefore
we need to make sure that signal is not muxed to the CSI_DATA_EN signal
internally and do so by steering it to the unused GPIO5_IO20.
We do this so that the kernel device-tree can properly define the signal for
RevB and beyond boards that do have this hooked up properly and require it.

The IMX6 Datasheets specifies that when the IMX6 LDO is enabled
(internal Anatop LDO's for VDD_ARM, VDD_SOC, and VDD_xPU) you need to
provide 1350mV on VDD_ARM_IN and VDD_SOC_IN for IMX6Q@1GHz (Automotive)
and 1275mV for IMX6DL@800MHz (Industrial). While we are still about 50mV
shy on the IMX6Q operating at 1GHz we set it to the max we can and leave it
up to the kernel to implement a regulator driver for the LTC3676 and put
the LDO's in bypass mode which allows us to drop the voltages by 125mV
respectively.
