The Kernel has mtd_read, mtd_write, mtd_erase and mtd_block_markbad.
Add these functions to barebox aswell to make future mtd synchronizations
with the kernel easier.

These are currently named mtd_read/write/erase. Functions with
the same name exist as global functions in the kernel. Rename
them to mtd_op_* to avoid name clashes with future mtd updates.

The kernel nowadays has mtd_read/write and other functions. In
barebox we also have these functions, but with a different prototype,
namely they correspond to the libmtd userspace functions. Rename
these functions to libmtd_* to avoid name clashes with future mtd
updates.

HSIC needs some special setup for i.MX6. Most ugly detail is that
the HSIC needs help of the IOMUX to configure a pullup on the strobe
line. This has to be done after the ehci controller has started.
Fortunately there is only one muxing possibility for the HSIC ports
on i.MX6, so we can simply control the iomux from the usbmisc driver.

Some controllers need an init hook after the USB controller is
started, so implement the post init hook for i.MX.

Having the board config file in /env/init has the problem that
the settings in /env/config are overwritten in the init sequence.
This moves the config-board files to /env/ and sources them explicitly
from /env/bin/init before sourcing /env/config

This is a rework of CLPS711X low level initialization code which includes:
- Prepare for changing CPU PLL multiplier from board lowlevel code.
- Decrease initial memory size to 8MB. It is minimal known size.
- Fix SDRAM initialization comment about size.
- Turn off all peripherals on startup.
- Skip PLL initialization if CPU is running from external 13 MHz clock.
- Use correct CPU speed for older CPUs without PLL.

The default setting for the imx28 watchdog is to do a power-off reset. If the
SoC is only powered via battery, then the watchdog powers the chip down, though.
According to the datasheet it should still be possible to execute a proper POR
with battery power, but testing showed otherwise.
When the watchdog power-off reset is disabled, a software reset is executed
instead. This works with and without battery power.
