[PATCH] ARM: pxa: Remove unused clock_enable field from struct pxa2xx_spi_master

[Jarkko Nikula <jarkko.nikula-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>]

Use for struct pxa2xx_spi_master clock_enable field was removed years ago
from the pxa2xx-spi driver by the commit 2f1a74e5a2de ("[ARM] pxa: make
pxa2xx_spi driver use ssp_request()/ssp_free()").

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

I propose this to be merged via ARM tree. I don't see we would need to do
other SPI related changes to struct pxa2xx_spi_master in near future (knock
on wood).
