pinctrl: amd: Fix use of undeclared identifier 'pinctrl_amd_s2idle_dev_ops'

`pinctrl_amd_s2idle_dev_ops` is hidden under both `CONFIG_ACPI` and
`CONFIG_PM_SLEEP` so the functions that use it need the same scope.

Adjust checks to look for both, and while updating make it CONFIG_SUSPEND
instead as that's what the ACPI header uses.
