The nvmem space defined in the ec code base for the cr50 board is used
by the TPM2 library, which has its own nvram size definition. The two
definitions must match.
On top of the fact that the definitions are not locked to each other,
there is a third completely unrelated nvram size definition in
board/cr50/board.c.
This patch unifies nvmem size definitions between cr50 and tpm2
repositories by adding a compile time check for the size to be the
same on both sides.
Also, it turns out that two certificates (RSA and ECC) together do not
quite fit into the cr50 TPM nvram. Hence the total allocated nvmem
space is being increased to 20K (note that the actual nvram size
available to the TPM is less than half of this).
