drivers: src: hwinfo: Report reset cause for lockup_sysresetreq Fix incomplete reset cause to be reported for NXP MIMXRT1062-evkb. In the event of a reset due to core lockup or software reset request on a 1062 board, the current NXP hwinfo driver reports an incomplete reset cause (only Ipp reset pin). This is happening because the 1062 uses a combined CPU lockup and system reset request register bit that should be checked, whereas the current driver only checks for the existence of a lockup-only status bit. This commit adds a check on the flag FSL_FEATURE_SRC_HAS_SRSR_LOCKUP_SYSRESETREQ already present in MIMXRT1062_features.h, to report such a reset cause should it occur.
