spi: amlogic-spifc-a1: Handle devm_pm_runtime_enable() errors

[ Upstream commit a90903c2a3c38bce475f46ea3f93dbf6a9971553 ]

devm_pm_runtime_enable() can fail due to memory allocation. The current
code ignores its return value, potentially causing runtime PM operations
to fail silently after autosuspend configuration.

Check the return value of devm_pm_runtime_enable() and return on failure.
