[PATCH] MIPS: loongson: fix random early boot hang

Some Loongson boards (e.g. Lemote FuLoong mini-PC) use ISA/southbridge device (CS5536 general purpose timer) for the timer interrupt. It starts running early and is already enabled during the PCI configuration, during which there is a small window in pci_read_base() when the register access is
