Ritesh Kumar d52b019c50 disp: msm: dsi: fix kasan out of bound in dsi reception ...

Fix out of bounds access that occurs when reading dsi
commands with custom non 4 bytes aligned payload.
When misaligned, the code is overfetching data due
to 32 bits reading constraint. This creates an offset
in receiving buffer. Using a local copy buffer large
enough to hold the extra bytes fixes the issue.
