Firmware and monitoring tools may not be ready to receive a CPER when we
read the bad pages, so send the CPERs at the end of RAS initialization
to ensure that the FW is ready to receive and process the CPER. This
removes the previous CPER submission that was added during bad page
load, and sends both in-band and out-of-band at the same time.

PMFW will manage RAS eeprom data by itself, add new interface to read
eeprom data via PMFW, we can read part of records by setting index.
v2: use IPID parse interface.
pa is not used and set it to a fixed value.
v3: optimize the null pointer check for IPID parse interface.

After the introduction of NPS RAS, one bad page record on eeprom may be
related to 1 or 16 bad pages, so the bad page record and bad page are
two different concepts, define a new variable to store bad page number.
