spi: sf: ICH SPI driver fix and SST25* changes

This series fix several bugs in current ICH SPI driver as well as adding byte program support for the SST25* flash.

Note only SST25* flash params are updated in patch #4 and #5 as an example. Other flash parts are untouched but can be updated after checking all flash parts' datasheets.

Simon, I can only test the ICH SPI driver with an ICH 7 compatible chipset. ICH 9 should work and it is appreciated if you could help testing and confirm it really does not break anything.

Bin Meng (5):
spi/ich.c: Fix a bug of reading from a non-64 bytes aligned address spi/ich.c: Set the rx operation mode for ich 7
spi: sf: Support byte program for sst spi flash
sf: Update SST25* flash params of supported read commands
sf: Update SST25* flash params of sector size & numbers
