timestamp: Bump CBMEM timestamp count, make full use of pre-RAM regions
Since we're reaching the timestamp limit on certain platforms (both for
the pre-RAM cache and the final CBMEM region), this patch increases the
amount of space for both. In the pre-RAM case, it achieves this by
always utilizing the full size of the TIMESTAMP() region allocated in
memlayout.ld, rather than arbitrarily limiting it to some constant.
BRANCH=None
BUG=None
TEST=Booted Oak and confirmed that I can once again see all pre-RAM
timestamps after picking in the LZ4 patch series.
