ARM: pxa: Remove unused clock_enable field from struct pxa2xx_spi_master

Browse source 
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.num_chipselect" field is used to determine the number of
