nautilus/poppy/soraka: Add support for dumping PMIC fault registers
If during PMIC initialization, it is identified that there was a VR
fault, then dump fault registers 0x16 and 0x17 to EC console. This
information is very useful during debugging sudden power losses in
field and so it is printed out to EC console.
Additionally, add panic reason with these register values as panic
data so that OS can provide this information in cros ec
panicinfo. This helps in retaining the information even if EC console
logs overflow.
BUG=b:65732924,b:69334392
BRANCH=None
TEST=Verified that on the failing Lux system, PMIC VR fault is
reported:"PMIC VRFAULT: PWRSTAT1=0x00 PWRSTAT2=0x01".
Also, verified that pmic fault register info is reported correctly in
panicinfo:
cat /sys/kernel/debug/cros_ec/panicinfo > /tmp/panicinfo
hexdump -n 1 -s 0x14 -e '"0x""%02X""\n"' /tmp/panicinfo
0x00
hexdump -n 1 -s 0x15 -e '"0x""%02X""\n"' /tmp/panicinfo
0x01
