stm32: Introduce define to control extended reset flags
Some ROs don't support extended reset flags saved in backup RAM.
BKPDATA_INDEX_SAVED_RESET_FLAGS_2 (introduced in CL:1295890) was added
in the middle of bkpdata_index enum, so it breaks compatibility between
RO and RW. In some cases, extended reset flags in backup RAM are cleared
because RO wrongly recognizes flags as panic reason.
BUG=b:119131962
BRANCH=none
TEST=Compile FPMCU firmware for nami with RO nami_fp_v2.2.144-7a08e07eb.
Issue 'reboot ro' command from RW part. FPMCU shouldn't stop
in RO, because that was not implemented when RO was released.
After jump to RW, check if panic data doesn't exist.
