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.
