spi: cadence-qspi: Try hard to disable the clocks

[ Upstream commit 612227b ]

In the remove path, we should try hard to perform all steps as we simply
cannot fail.

The "no runtime PM" quirk must only alter the state of the RPM core, but
the clocks should still be disabled if that is possible. Move the
disable call outside of the RPM quirk.
