[PATCH V1] clk: imx8mp: Alias M7 SRC/DIV to M7 CORE

[PATCH V1] clk: imx8mp: Alias M7 SRC/DIV to M7 CORE

[LI Qingwu]

Defined IMX8MP_CLK_M7_SRC and IMX8MP_CLK_M7_DIV in imx8mp-clock.h
but never assigned. It will cause the system to hang if using it.
Alias IMX8MP_CLK_M7_SRC and IMX8MP_CLK_M7_DIV to IMX8MP_CLK_M7_CORE
for backward compatibility.

Thanks, I will and Fixes in V2
Fixes: 8c83a8ff4dd9 (clk: imx8mp: use imx8m_clk_hw_composite_core to simplify code)
