[PATCH] cpm_uart: use DPRAM for early console
m8xx_cpm_hostalloc() can't rely on using the coherent DMA allocator early
on boot because the VM is not fully up yet. Change it to use the on-board
DPRAM instead.
The current code relies on the "bootmem_page" allocated by
m8xx_cpm_reset(), which must be killed.
This is done in v2.4 but has never been forward ported to v2.6.
