pinctrl: Don't allow PINCTRL_AMD to be a module

pinctrl: Don't allow PINCTRL_AMD to be a module

It was observed that by allowing pinctrl_amd to be loaded
later in the boot process that interrupts sent to the GPIO
controller early in the boot are not serviced.  The kernel treats
these as a spurious IRQ and disables the IRQ.

This problem was exacerbated because it happened on a system with
an encrypted partition so the kernel object was not accesssible for
an extended period of time while waiting for a passphrase.

To avoid this situation from occurring, stop allowing pinctrl-amd
from being built as a module and instead require it to be built-in
or disabled.
