media: venus: firmware: Leave a clue about obtaining CP VARs

Browse source

The qcom_scm_mem_protect_video_var accepts two sets of <addr size>
pairs as arguments. They describe the virtual address ranges of the
CP (Content Protection) and CP_NONPIXEL regions. It is however not
immediately obvious how to obtain these values.

Leave a comment explaining how one can translate the vendor device
tree properties for use with the mainline driver.
