[PATCH v1 1/5] spi: pxa2xx: Move number of CS pins validation out of condition

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

There is no need to allocate chip_data and then validate number of
CS pins as it will have the same effect. Hence move number of CS pins
validation out of condition in setup().
