While it's fine to make such change for controls up to V4L2_CID_MPEG_VIDEO_HEVC_HIER_CODING_L6_QP...

...for the controls below we may need to replace "Lay" with "L." 
to make sure the length of the string don't exceed 31 characters 
(32 with terminating NULL). The names below seem to be 1 character 
too long and will be truncated when running VIDIOC_QUERY_CTRL ioctl.
