[PATCH 2/2] clk: clk-imx8qm: Add LPUART IPG entries

[Fabio Estevam]

Since commit cc7df0b9e8bc ("serial: lpuart: Enable IPG clock") 
the apalis-imx8qm board no longer boots.

The reason is that the imx8qm clock driver does not handle the
LPUART IPG clocks inside get_rate(), set_rate() and enable() functions.

Fix the boot regression by adding the LPUART IPG entries.
