pinctrl: amd: Take suspend type into consideration which pins are non-wake
Some laptops have pins which are a wake source for S0i3/S3 but which
aren't a wake source for S4/S5 and which cause issues when left unmasked
during hibernation (S4).
For example HP EliteBook 855 G7 has pin #24 that causes instant wakeup
(hibernation failure) if left unmasked (it is a wake source only for
S0i3/S3).
GPIO pin #24 on this platform is likely dedicated to WWAN XMM7360
modem since this pin triggers wake notify to WWAN modem's parent PCIe
port.
Fix this by considering a pin a wake source only if it is marked as one
for the current suspend type (S0i3/S3 vs S4/S5).
Since Z-wake pins only make sense at runtime these were excluded from
both of suspend categories, so pins with only the Z-wake flag set are
effectively treated as non-wake pins.
Fixes: 2fff0b5e1a6b ("pinctrl: amd: Mask non-wake source pins with interrupt enabled at suspend")
