imx: imx8ulp: cgc: Switch to NICLPAV to FRO192 before PLL4 init

When reset with dual boot mode, the LPAV domain won't power down
due to its master is not assigned to APD. So the NICLPAV keeps the
last setting to use PLL4PFD1. So before SPL initialize the PLL4,
we need to switch NICLPAV to FRO192, otherwise system will hang.
