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

[Mario Limonciello]

From: Mario Limonciello <mario.limonciello@amd.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.

Shouldn't this be CONFIG_SUSPEND given what's going on in acpi.h?

Also, there is one more report regarding pinctrl_dev being unused:

https://lore.kernel.org/linux-acpi/202504101106.hPCEcoHr-lkp@intel.com/T/#u

Any chance to address all of this in one patch?

Really - I think we probably should change all of pinctrl-amd.c to use 
CONFIG_SUSPEND.

Sure; I'll spin again and get something out to cover both cases soon.
