Dropped - sh_spi driver - CONFIG_SH_SPI,SH_SPI_BASE

Dropped due to: - no active updates - no dm conversion - multiple pings for asking dm-conversion - no response for dm converted patch - driver-model migration expiry

Signed-off-by: Jagan Teki jagan@amarulasolutions.com --- Changes for v3: - rebase on master
