Subject: clk: imx: add configuration option for mmio clks
Git-commit: 3a48d918a4615f0287ac2e106981b3987bf75a3d
Patch-mainline: v5.0-rc1
References: FATE#326248

The patch introduces CONFIG_MXC_CLK option for legacy MMIO clocks,
this is required to compile legacy MMIO clock conditionally when adding
SCU based clocks for MX8 platforms later.
