pinctrl/amd: save pin registers over suspend/resume
The touchpad in the Asus laptop models X505BA/BP and X542BA/BP is
unresponsive after suspend/resume. The following error appears during
resume:
i2c_hid i2c-ELAN1300:00: failed to reset device.
The problem here is that i2c_hid does not notice the interrupt being
generated at this point, because the GPIO is no longer configured
for interrupts.
Fix this by saving pinctrl-amd pin registers during suspend and
restoring them at resume time.
Based on code from pinctrl-intel.
