If compiled with logging and debug UART support, the following is printed: serial_msm serial@78af000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
This is due to the fact that IPQ4019 pinctrl driver is not available prior to relocation and thus MSM serial will fail probing as pinctrl provider is not available.
So, lets enable DM_FLAG_PRE_RELOC for IPQ4019 pinctrl to fix this.
