[PATCH v2 0/5] spi: cadence-qspi: Fix runtime PM and system-wide suspend

[Théo Lebrun]

Hi,

This fixes runtime PM and system-wide suspend for the cadence-qspi
driver. Seeing how runtime PM and autosuspend are enabled by default, I
believe this affects all users of the driver.

The initial change has been split into three commits and a fourth commit
is added to add system-wide suspend/resume callbacks.

The MIPS platform at hand, used for debugging and testing, is currently
not supported by the driver. It is the Mobileye EyeQ5 [0]. No code
changes are required for support, only a new compatible and appropriate
match data + flags. That will come later, with some performance-related
patches.

TODO: changelog below

Thanks all,
Théo
