drm/amd/display: Fix LSDMA divide by zero
[WHY]
element_size_to_bytes_per_pixel() handled only element sizes 0 to 4 and
returned 0 for every other value, and an unexpected element size caused
a divide by zero.
[HOW]
Derive the size as 1 << element_size, which matches the existing
encoding, and fall back to 1 for values of 8 or more to keep the result
nonzero.
