spi: pxa2xx: derive struct chip_data from struct drv_data

Since we call pxa2xx_ssp_get_clk_div() from pump_transfers() we may derive pointer to struct chip_data from struct drv_data like it's done in the rest of the functions. This will make it less errorprone. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Jarkko Nikula <[email protected]> Signed-off-by: Mark Brown <[email protected]>
