msm: mdss: correct bpp for TP10 in bandwidth calculations



Current driver uses a 1.5 bpp for bandwidth calculations
in any format with 420 chroma sample. This is wrong for
TP10 pixel format, where we need to use 2 bpp.
Fix this issue by making sure driver uses the correct
bpp for this pixel format.
