powerpc/85xx: Read board switch settings on p1_p2_rdb
PCA9557 is parallel I/O expansion device on I2C bus which stores various
board switch settings like NOR Flash-Bank selection, SD Data width.
On board:
switch SW5[6] is to select width for eSDHC
ON - 4-bit [Enable eSPI]
OFF - 8-bit [Disable eSPI]
switch SW4[8] is to select NOR Flash Bank for Booting
OFF - Primary Bank
ON - Secondary Bank
Read board switch settings on p1_p2_rdb and configure corresponding
eSDHC width.
