Subject: [PATCH] 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 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.
