Current clocks tree definition for CPSW/CPTS doesn't
correspond TRM for dra7/am57 SoCs.
CPTS: has to be sourced from gmac_rft_clk_mux clock
CPSW: DPLL_GMAC -> CLKOUT_M2 -> GMAC_250M_CLK -> 1/2 ->
-> GMAC_MAIN_CLK (125 MHZ)
Hence, correct clock tree for GMAC_MAIN_CLK and use proper
clock for CPTS. This also require updating of CPTS clock
multiplier.
