Update vpd read and write flow

The commit implement changes to log Pel and call out
FRU and record in case of any ECC failure while reading
the vpd data for the FRU and continue with the processing
of rest of the records.

In case of write, BMC reboot is blocked till the VPD is
updated. Doing this will restrict any data/Ecc corruption
due to BMC reboot while VPD data is being updated.

Tested:
Corrupted vpd for tpm_wilson then triggered collection of
vpd for the FRU.
Pel was logged calling out the FRU
