The mx51evk u-boot has an issue that system will get reset
every 2 hours.
MC13892 has an inside charge timer which expires in 120 minutes.
If ICHRG and CHGAUTOB are not set properly, this timer expiration
will get system power recycled.
Since mx51evk has no Li-Ion battery on board, the patch sets
ICHRG in externally powered mode and sets CHGAUTOB bit to avoid
automatic charging, so that system will not get reset by this
timer expiration.
The patch also corrects the bit field definition of register 48
(Charger 0) per latest MC13892 Reference Manual.

As stated in 2720178533,
the mx51evk has not CPLD and all references must be removed.
This patch drop a .h file that still remains in board
directory.

The patch removes warnings at compile time and provides
some cleanup code:
- Removed comment on NAND (not yet supported) from lowlevel_init.S
- Removed NFMS bit definition from imx-regs.h
The bit is only related to MX.25/35 and can lead to confusion
- Moved is_soc_rev() to soc specific code (removed from mx51evk.c)
