Add suspend to ram support for PCIe on J7200

This add suspend to ram support for the PCIe (RC mode) on J7200
platform.
In RC mode, the reset pin for endpoints is managed by a gpio expander
on a i2c bus. This pin shall be managed in suspend_noirq and
resume_noirq.
The suspend/resume has been moved to suspend_noirq/resume_noirq for
pca953x (expander) and pinctrl-single.
To do i2c accesses during suspend_noirq/resume_noirq, we need to force
the wakeup of the i2c controller (which is autosuspended) during
suspend callback.
It's the only way to wakeup the controller if it's autosuspended, as
runtime pm is disabled in suspend_noirq and resume_noirq.
