[PATCH] spi: rpc-if: Gaurd .pm assignment with CONFIG_PM_SLEEP #ifdef check

[Lad Prabhakar]

With CONFIG_PM_SLEEP disabled the rpcif_spi_pm_ops variable is still
referenced and thus increasing the size of kernel.

Fix this issue by adding CONFIG_PM_SLEEP #ifdef check around the .pm
assignment (image size is critical on RZ/A SoC's where the SRAM sizes
range 4~5 MiB).
