[target/msm7630]: Add code to auto detect interleaved mode.
Interleaved mode is identified using the build id provided
in shared memory. Configure the ptable entries for interleaved mode.
Configure GPIOs for the second NAND device. Add code to modify
the page size when operating in interleaved mode.
