video/hdmi: Reorder fields in 'struct hdmi_avi_infoframe'

Group some variables based on their sizes to reduce hole and avoid padding.
On x86_64, this shrinks the size of 'struct hdmi_avi_infoframe'
from 68 to 60 bytes.

It saves a few bytes of memory and is more cache-line friendly.

This also reduces the union hdmi_infoframe the same way.
