clk: ti: dra7: fix "failed to lookup clock node gmac_gmii_ref_clk_div" boot message

commit f8d17344a60921c2387759fc0a85aa64299d1ec6 upstream.

Prevent creating clk alias for non existing gmac_gmii_ref_clk_div clock and,
this way, eliminate excessive error message during boot:

 "ti_dt_clocks_register: failed to lookup clock node gmac_gmii_ref_clk_div"
