FROMLIST: clk: rockchip: rk3036: fix and add node id for emac clock
Due to referred old version TRM, there is incorrect emac clock node,
we should fix it. The SEL_21_9 is the parent of SEL_21_4.
In the emac driver, we need to refer HCLK_MAC, and because There are
only 3PLLs (APLL/GPLL/DPLL) on the rk3036, most clock are under the
GPLL, and it is unable to provide the accurate rate for mac_ref which
need to 50MHz probability, we should let it under the APLL and are
able to set the freq which integer multiples of 50MHz, so we add these
emac node for reference.
