[PATCH 11/11] board: freescale: p1_p2_rdb_pc: Add env commands norlowerboot, norupperboot, sd2boot and defboot

[Pali Rohár]

All *boot env commands overrides default BootROM boot location via i2c.
BootROM then starts booting U-Boot from this specified location instead of
the default one.

Add new env command defboot which reverts BootROM boot location to the
default value, which in most cases is configurable by HW DIP switches.

And add new env commands norlowerboot, norupperboot, sd2boot to boot from
other locations. norlowerboot would instruct BootROM to boot from lower NOR
bank, norupperboot from upper NOR bank and sd2boot from SD card with
alternative configuration.
