Since i.MX common clk driver will support module build and no longer selected by default, so for i.MX ARMv7 platforms, need to manually select it to make build pass. Changes since V1: - Fix build error for x86_64-allyesconfig by adding dependency for MXC_CLK_SCU; - Move lpcg clock driver change to SCU patch, this is incorrect in V1.
