clk: imx: imx8qxp-lpcg: add parsing clocks from device tree
One LPCG controller supports up to 8 clock outputs while each of them
is fixed to 4 bits. It supports only gating function with fixed bits.
So we can use the clk-indices to fetch the corresponding clock idx from
device tree. With this way, we can write a generic LPCG clock drivers.
This patch add that support to parse clocks from device tree.
