AMD S3 resume: Add framwork to write bigger data

This patch is based on 'AMD S3: Program the flash in a bigger data packet'[1]

Some AMD south bridge can write bigger data when saving S3 info.
    In this patch, I use config 'AMD_SB_SPI_TX_LEN' to contral data size.
    AMD_SB_SPI_TX_LEN is defined in 'src/southbridge/amd/Kconfig'
    and then can be overridden in the Kconfig for specific
    southbridges that support larger size.

I have tested on AMD Parmer and Thatcher. We will release a new board
    whose south bridge can transfer more than 4 bytes each time.
