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.
