tpm2: add nvmem data to the right segment
Modules in board/cr50/tpm2 are part of the TPM task, and their .bss
segment needs to be wiped out along with other TPM modules' when TPM
is reset.
The only module from this directory which has static variables is
NVMem.c. This patch groups the variables into a structure, and makes
sure that the structure is stored in the part of .bss which is zeroed
when TPM is reset.
BRANCH=none
BUG=none
TEST=verified that TPM wipeout happening during RMA reset is
successful.
