drm/i915: Avoid clearing the base drm_crtc_state

Browse source

To prevent having to preserve the drm_crtc_state as we clear the
intel_crtc_state, only memset our extended state.

Fixes:
drivers/gpu/drm/i915/intel_display.c: In function ‘clear_intel_crtc_state’:
drivers/gpu/drm/i915/intel_display.c:11301:1: error: the frame size of 1056 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

v2: Add a comment and BUILD_BUG_ON to explain the memset()
