[Intel-gfx] [PATCH] drm/i915: drop alpha_support for good in favour of force_probe

[Jani Nikula]

It's been a long enough transition period since the DRM_I915_FORCE_PROBE
config and i915.force_probe module parameter were introduced in commit
7ef5ef5cdead ("drm/i915: add force_probe module parameter to replace
alpha_support"). Remove alpha support.
