ARM: pxa: Remove unused clock_enable field from struct pxa2xx_spi_master 

Use for struct pxa2xx_spi_master clock_enable field was removed years ago
from the pxa2xx-spi driver by the commit 2f1a74e5a2 ("[ARM] pxa: make
pxa2xx_spi driver use ssp_request()/ssp_free()").

Therefore remove it from structure definition, documentation and from
couple affected board files.

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".
The "pxa2xx_spi_master.num_chipselect" field is used to determine the number of
slave device (chips) attached to this SPI master.
