drm/msm/hdmi: also send the SPD and HDMI Vendor Specific InfoFrames

Browse source

Extend the driver to send SPD and HDMI Vendor Specific InfoFrames.

While the HDMI block has special block to send HVS InfoFrame, use
GENERIC0 block instead. VENSPEC_INFO registers pack frame data in a way
that requires manual repacking in the driver, while GENERIC0 doesn't
have such format requirements. The msm-4.4 kernel uses GENERIC0 to send
HDR InfoFrame which we do not at this point anyway.
