Subject: [PATCH v2] pinctrl: amd: Fix use of undeclared identifier 'pinctrl_amd_s2idle_dev_ops'

From: Mario Limonciello <mario.limonciello@....com>

`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.

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202504100420.88UPkUTU-lkp@intel.com/

v2:
 Use CONFIG_SUSPEND instead of CONFIG_PM_SLEEP
