ipq5332: Skip PCIe enumeration during the board_init

Browse source 
In Q6, we are seeing rare PCIe enumeration failure and suspecting
U-boot PCIe enumeration (Gen1) could impact. Hence skipping the PCIe
enumeration during the board_init based on CONFIG_IPQ_PCI_INIT_DEFER
config and added it after autoboot is stopped.
