vpp: increase the afbc burst len as 4 for txlx [1/1]

PD#TV-3132

Problem:
When playing 4K afbc and scaling down to small window,
the vskip is 1 and DDR freq is also lower, the display will
flicker caused by DDR bandwidth issue.

Solution:
Increase the afbc mif burst len from 2 to 4. And enable
the dmc adjustment in that case.

Verify:
r311, verify pass
