[Intel-gfx] [PATCH] drm/i915/dp: Don't roundup max bpp, while computing compressed bpp

[Intel-gfx] [PATCH] drm/i915/dp: Don't roundup max bpp, while computing compressed bpp

[Ankit Nautiyal]

While computing compressed bpp, maximum value of bits_per_pixel is
calculated that can be supported with the given link configuration
for a given mode. Avoid rounding up of this max bits_per_pixel.
Also improve documentation for computing max bits_per_pixel.
