dccg35_set_hdmistreamclk_src_new() updates HDMISTREAMCLK_CNTL but
passes DPSTREAMCLK0_SRC_SEL as the field identifier in the second
REG_UPDATE_2 slot.
The current behavior is harmless on DCN3.5 because both fields share the
same bit layout, but it is still incorrect and could break on future
hardware revisions.
