Instead of introducing new functions each time a new power supply
situation is to be added, this patch adds parameters to mx28_power_init.
Right now there are three parameters:
- has_battery - true when this board has a battery.
- use_battery_input - true when this board is supplied from the
battery input, but has a DC source instead of a real battery
- use_5v_input - true when this board can use the 5V input
The third one is introduced with this patch and allow to boot a board from 5v
(USB) source only. The main necessary change this needs is that the DC-DC
converter must always be sourced from DCDC_4P2 (DROPOUT_CTRL field of
HW_POWER_DCDC4P2)

The file drivers/pinctrl/pinctrl.c is compiled only when
CONFIG_PINCTRL is defined. "IS_ENABLED(CONFIG_PINCTRL)" is
always evaluated as 1 in this function.
(Although the compiler would optimize it, the source file does
not look nice.)

Since include/linux/linkage.h includes <asm/linkage.h>, the basic
coding style we should follow is:
- <linux/linkage.h> should contain default macro defines
- <asm/linkage.h> can define arch-specific macros and override the
default ones in <linux/linkage.h>
The arch/blackfin/include/asm/linkage.h has redundant defines that
are already defined in <linux/linkage.h>.
Replace it with the one imported from Linux 3.19-rc6.
Generally, <asm/linkage.h> should not be included directly.

The i.MX6 NAND update handler sets all bytes of OOB data to 0x00 in pages that
contain the FCB structure currently. So the first and second byte which is
used as the manufacturers bad block marker is in the 'bad block' state. A scan
for factory bad blocks will detect these blocks as bad while they are still ok.
The barebox issues a scan for factory bad blocks to rebuild the bad block table
if the NAND is brand new or the last four blocks of flash are erased.
To fix this problem set the first two bytes of OOB data to 0xFF explicitly.
There is a potential chance that the bbu handler will mark a real bad block as
factory good. That's not a problem for the ROM Loader, because the FCB is
protected by a checksum and the hamming_13_8 encoding. Additionally the current
implementation of the bbu handler does not check the bad block table or the
factory bad block marker before writing the FCB at the first page of the first
and second block.
