linux-ti33x-psp 3.2: switch ADC to 16x averaging, disable 275MHz, add 4.3" LCD support

Browse Source 
* The switch to 16x averaging is done to combat the excessive noise in the
  signal. It's still *very* bad, but the TS cursor jitter has decreased a bit
* The OPP for 275MHz was disabled due to all the errata. Both the EMIF and MUSB
  don't seem to like that OPP.
* The resistive touch version of the 4.3" LCD cape is supported in 24 bit mode.
