Right now TLB entry 0 ist used as UART0 mapping for the early debug output (via CONFIG_SERIAL_TEXT_DEBUG). This causes problems when many TLB's get used upon Linux bootup (e.g. while PCIe scanning behind bridges and/or switches on 440SPe platforms). This will overwrite the TLB 0 entry and further debug output's may crash/hang the system. This patch moves the early debug UART0 TLB entry from 0 to 62 as done in arch/powerpc. This way it is in the "pinned" area and will not get overwritten. Also the arch/ppc/mm/44x_mmu.c code is now synced with the newer code from arch/powerpc.
