lcd: ancora: Adjust porch values for rev. 2 panels

 * Newer Android versions are more intensive on the display
   and might cause underflow (blue flashing) under stress
   situations. Adjust the porch values to minimize this.

   Values might not be 100% optimal though, but we can finetune
   it later if needed.
lcdc:ancora:Adjust porch values for rev. 1 panels too * rev. 1 panels are affected by blue screen issue too
