OMAP4: OMAPDSS: Request higher bandwidth for 1080p FB

Request higher L3 bandwidth when we have 1080p, or higher,
resolution framebuffer. This is done to avoid underflow on
DSS pipelines.

OMAPDSS: DSS: Relax L3 bus bandwidth constraint

In a current codebase L3 BW constraint is set if
any display has resution higher or equal FullHD.

Estimated available DSS bandwidth on L3@OPP50 is ~800MB/s.
It is approximately 3 WXGA layers or almost 1.5 FullHD layers at
60fps rate.

This patch relaxes L3 BW constraint and set it only
if current overlays' configuration needs higher BW.

OMAPDSS: DISPC: do not lose taps selection

Move taps selection logic before scaling check, so 3- of 5-tap always
get selected, no metter whether we do scaling or not.
