[PATCH] drm/amd: Avoid running psp_ras_initialize() on HW without RAS

[Mario Limonciello]

On hardware known not to have RAS or in cases that a user has disabled
RAS via kernel module parameter, it makes no sense to try to run code
from psp_ras_initialize().  Furthermore trying to run it shows the
following message on every boot:

`RAS: optional ras ta ucode is not available`

Avoid running the rest of the function is RAS is not available.
