spi: sh-msiof: Add runtime PM lock in initializing

commit 01576056 upstream.

SH-MSIOF driver is enabled autosuspend API of spi framework.
But autosuspend framework doesn't work during initializing.
So runtime PM lock is added in SH-MSIOF driver initializing.

Fixes: e2a0ba54 (spi: sh-msiof: Convert to spi core auto_runtime_pm framework)
