Subject: drm/i915/vga: switch to use VGA definitions from video/vga.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The video/vga.h has macros for the VGA registers. Switch to use them.

v2: Use direct 0x01 instead of the confusing VGA_SEQ_CLOCK_MODE (Ville)
