Subject: gpu/drm: ingenic: Set max FB height to 4095
Git-commit: 96ea0ae692fe382dc7a5d66289d8fbd4a369614d
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
While the LCD controller can effectively only support a maximum
resolution of 800x600, the framebuffer's height can be much higher,
since we can change the Y start offset.
v2: No change
