Alison Wang c207ff6129 arm: ls102xa: Remove bit reversing for SCFG registers
SCFG_SCFGREVCR is SCFG bit reverse register. This register
must be written with 0xFFFFFFFF before writing to any other
SCFG register. Then other SCFG register could be written in
big-endian mode.

Address: 157_0000h base + 200h offset = 157_0200h

SCFGREV SCFG Bit Reverse Control Filed
32'h 0000_0000 - No bit reverse is applied
32'h FFFF_FFFF - Bit reverse is applied; so 31:0 will be stored/read as
0:31

This patch removes the bit reversing for SCFG registers in
u-boot. It will be implemented through PBI commands in RCW
.pbi
write 0x570200, 0xffffffff
.end
So other SCFG register could be written in big-endian mode
in u-boot or kernel directly.
