René Rebe c61afb99c8 fbdev: ffb: fix corrupted video output on Sun FFB1 
[ Upstream commit b28da0d092461ac239ff034a8ac3129320177ba3 ]

Fix Sun FFB1 corrupted video out ([1] and [2]) by disabling overlay and
initializing window mode to a known state. The issue never appeared on
my FFB2+/vertical nor Elite3D/M6. It could also depend on the PROM
version.

/SUNW,ffb@1e,0: FFB at 000001fc00000000, type 11, DAC pnum[236c] rev[10] manuf_rev[4]
