Subject: [PATCH v2] drm/pl111: Actually fix CONFIG_VEXPRESS_CONFIG depends

VEXPRESS_CONFIG needs to either be missing, built-in, or modular when
pl111 is modular. Update the Kconfig to reflect the need.

Fixes: 4dc7c97d04dc ("drm/pl111: depend on CONFIG_VEXPRESS_CONFIG")

v2: use expected Kconfig style to express this. :)

Since I screwed up already, care to also push this to drm-misc-next?
