drm/edid: fix and clarify HDMI VSDB audio latency parsing
Add helpers for Latency_Fields_Present and I_Latency_Fields_Present
bits, and fix the parsing:
- Respect specification regarding "I_Latency_Fields_Present shall be
zero if Latency_Fields_Present is zero".
- Don't claim latency fields are present if the data block isn't big
enough to hold them.
