Subject: OMAPDSS: split hdmi muxing function

Split the omap4_hdmi_mux_pads() function into two parts, one handles the
tpd12s015 gpio muxing, the other handles the hdmi pins.

This is clearer, as hdmi and tpd12s015 are separate devices, and it also
allows us to mux those separately with DT.

Subject: da8xx-fb: cleanup LCDC configurations

Configure below LCDC configurations to optimal values, also have an
option configure these optional parameters for platform.
1) AC bias configuration: Required only for passive panels
2) Dma_burst_size:
3) FIFO_DMA_DELAY:
4) FIFO threshold: Does not apply for da830 LCDC.

Patch is verified for 16bpp and 24bpp configurations on da830, da850 and
am335x EVMs.

Subject: video: da8xx-fb: clk_get on connection id fck

do clk_get on connection id "fck" to support OMAP based
platforms having multiple clocks for module. Without this
driver change clk_get fails on am335x.

This patch is based on the discussion in community
