Haotian Zhang 44309fda9c mtd: rawnand: renesas: Handle devm_pm_runtime_enable() errors 
[ Upstream commit a3623e1ae1 ]

devm_pm_runtime_enable() can fail due to memory allocation failures.
The current code ignores its return value and proceeds with
pm_runtime_resume_and_get(), which may operate on incorrectly
initialized runtime PM state.

Check the return value of devm_pm_runtime_enable() and return the
error code if it fails.

Fixes: 6a2277a0eb ("mtd: rawnand: renesas: Use runtime PM instead of the raw clock API")
