Set activation periods as 64 cdclk sync up with KMS
We use force CRT detect trigger bit(1 << 3) to detect VGA in hot plug mode,
which triggers a CRT hotplug/unplug detection cycle independent of the
interrupt enable bit(1 << 9), so keep bit 9.
And although spec says CRT_HOTPLUG_ACTIVATION_PERIOD_64(1 << 8) is only useful
for mobile platform, it is also required to detect vga on G4x platform correctly.
Tested the patch on G45/G43/Q45 platforms with no regressions
It fixed freedesktop.org bug #21120 and part of bug #21210.
