Jocelyn Falempe 99f08ff40c drm/mgag200: Fix PLL setup for G200_SE_A rev >=4
commit b389286d02 upstream.

For G200_SE_A, PLL M setting is wrong, which leads to blank screen,
or "signal out of range" on VGA display.
previous code had "m |= 0x80" which was changed to
m |= ((pixpllcn & BIT(8)) >> 1);

Tested on G200_SE_A rev 42

This line of code was moved to another file with
commit 877507bb95 ("drm/mgag200: Provide per-device callbacks for
PIXPLLC") but can be easily backported before this commit.

v2: * put BIT(7) First to respect MSB-to-LSB (Thomas)
    * Add a comment to explain that this bit must be set (Thomas)

Fixes: 2dd040946e ("drm/mgag200: Store values (not bits) in struct mgag200_pll_values")
