CBMEM: Fix allocation for static CBMEM

Browse Source 
CBMEM console buffer size is adjustable in menuconfig, but this would
not correctly adjust the overall allocation made for CBMEM.

HIGH_MEMORY_SIZE is aligned to 64kB and definitions are moved down in
the header file as HIGH_MEMORY_SIZE is not used with DYNAMIC_CBMEM.

Try to continue boot even if CBMEM cannot be created. This error would
only occur during development of new ports anyways and more log output
is better.
