spi/xilinx: Eliminate pdata references from common code.
The current code has the OF binding modifying the platform_data pointer which it must not do, and the common code doesn't really need to use a pdata pointer. This patch eliminates the platform_data references from the common part of the driver in preparation for merging the OF and non-OF versions.
