media: v4l: common: Fix naming of v4l2_get_link_rate 

Rename v4l2_get_link_rate() as v4l2_get_link_freq(). What the function
returns is the frequency of the link; rename it to reflect the name of the
control where the information is obtained.

Fixes: 1b888b3ceb ("media: v4l: Add a helper for obtaining the link frequency")
