drm: tilcdc: Replace drm_fb_get_bpp_depth() with drm_format_plane_cpp()

Browse Source 
The driver needs the number of bytes per pixel, not the bpp and depth
info meant for fbdev compatibility. Use the right API.

In the tilcdc_crtc_mode_set() function compute the hardware register
value directly from the pixel format instead of computing the number of
bits per pixels first.
