The "pxa2xx_spi_master.ssp_type" field must have a value between 1 and 3 and
informs the driver which features a particular SSP supports.

The "pxa2xx_spi_master.clock_enable" field is used to enable/disable the
corresponding SSP peripheral block in the "Clock Enable Register (CKEN"). See
the "PXA2xx Developer Manual" section "Clocks and Power Management".
