[PATCH 17/23] media: atomisp: Remove gmin_platform VCM code.

[Hans de Goede <hdegoede@redhat.com>]

VCM support has already been removed from the main atomisp driver
in commit 7473c97dd8d0 ("media: atomisp: Remove custom VCM handling")
remove the left-over dead VCM handling from the gmin platform code.
