Since commit cc7df0b9e8bc ("serial: lpuart: Enable IPG clock") the colibri-imx8qxp board no longer boots.
The reason is that the imx8qxp 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.
