pci-legacy systems are not using logic_pio to managed PIO allocations, thus the generic pci_address_to_pio won't work when PCI_IOBASE is defined.
Override the function to use architecture implementation to fix the problem.

Hello,
Tested on:
- mips64el, QEMU malta - RTC is working, no suspicious warnings in dmesg,
- mipsel, QEMU malta - RTC is working, no suspicious warnings in dmesg,
- fuloong2e_defconfig, in QEMU on Ubuntu 24.04 - kernel does not boot, with or without this patch:

- loongson3_defconfig, in QEMU (target loongson3-virt) - no important differences in dmesg output, but this platform does not use RTC CMOS, but a Goldfish RTC,
Greetings,
