[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
