[U-Boot] [PATCH] spi: mxs: Allow other chip selects to work

MXS SSP controller may have up to three chip selects per port: SS0, SS1 and SS2. Currently only SS0 is supported in the mxs_spi driver. Allow all the three chip select to work by selecting the desired one in bits 20 and 21 of the HW_SSP_CTRL0 register. Signed-off-by: Fabio Estevam
