drm/i915/display: Consider fractional vdsc bpp while computing m_n values
MTL+ supports fractional compressed bits_per_pixel, with precision of
1/16. This compressed bpp is stored in U6.4 format.
Accommodate this precision while computing m_n values.
v1:
Replace the computation of 'data_clock' with 'data_clock =
DIV_ROUND_UP(data_clock, 16).' (Sui Jingfeng).
v2:
Rebase and pass bits_per_pixel in U6.4 format.
