[U-Boot] [PATCH 31/34] spi: Zap omap3_spi driver-related code

[Jagan Teki <jagan@amarulasolutions.com>]

Dropped
- omap3_spi driver
- SPI, SPI flash CONFIG-items
- CMD_SPI, CMD_SF..etc

Dropped becuase
- no active updates
- no dm conversion
- no reponse for dm converted patch
- driver-model migration expiry
