[PATCH] ppc32 CPM_UART: various fixes for pq2 uart users

This fixes various odd things that missed update together with cpm_uart
platform_device move. Unified resources names, restructurisation, etc.
Also, addressed issue with recent phys/virt translation rework. Being
cache-coherent, CPM2's do alloc_bootmem() for the console stuff, and it was
used to treat console buffer descriptor mapping 1:1 (as in CPM1 case),
which is definitely wrong.
