The msm_dp_utils_pack_sdp_header() accepts an unlimited-size u32 pointer
for the header output, while it expects a two-element array. It performs
a sizeof check which is always true on 64-bit platforms (since
sizeof(u32*) is 8) and is always false on 32-bit platforms. It returns
an error code which nobody actually checks.
Fix the function interface to accept u32[2] and return void, skipping
all the checks.

This was included in -fixes as well. So no need to include.
