[PATCH v5 04/11] clk: Ingenic: Fix problem of MAC clock in Ingenic X1000 and X1830.

[周琰杰 (Zhou Yanjie)]

X1000 and X1830 have two MAC related clocks, one is MACPHY, which is
controlled by MACCDR register, the other is MAC, which is controlled
by the MAC bit in the CLKGR register (with CLK_AHB2 as the parent).
The original driver mistakenly mixed the two clocks together.
