powerpc: move ADDR_MAP to Kconfig

Move ADDR_MAP related config options from include/configs/*.h to the
proper place in lib/Kconfig. This has been done using
./tools/moveconfig.py and manual inspection of the generated changes.
This is a preparation to use ADDR_MAP helper on ARM 32bit Raspberry Pi4
board for mapping the PCIe XHCI MMIO, which is above the 4GiB identity
mapping limit.
