watchdog: npcm: add bootstatus support
The NPCM750 uses RESSR and the NPCM845 uses INTCR2 to latch reset
indications. Read those bits during probe and map them into watchdog
bootstatus flags.
For NPCM845, cache the sampled INTCR2 state in SCRPAD10 after the reset
status bits are cleared so later probes can report the same boot-time
state. Also report WDIOF_CARDRESET for the watchdog instance whose reset
bit is latched, while leaving WPCM450 behavior unchanged.
