[ARM] pxa: make pxa2xx_spi driver use ssp_request()/ssp_free()
1. make pxa2xx_spi.c use ssp_request() and ssp_free() to get the common information of the designated SSP port. 2. remove those IRQ/memory request code, ssp_request() has done that for the driver 3. the SPI platform device is thus made psuedo, no resource (memory/IRQ) has to be defined, all will be retreived by ssp_request() 4. introduce ssp_get_clk_div() to handle controller difference in clock divisor setting 5. use clk_xxx() API for clock enable/disable, and clk_get_rate() to handle the different SSP clock frequency between different processors Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
