Add additional FLASH Fault bits to dectect faults from chip.
Some Flash drivers support UVLO, IVFM, NTC Trip faults.
UVLO :  Under Voltage Lock Out Threshold crossed
IVFM :  IVFM block reported and/or adjusted LED current Input Voltage Flash 
Monitor trip threshold
NTC  :  NTC Threshold crossed. Many Flash drivers have a pin and the fault bit 
to 
serves as a threshold detector for negative temperature coefficient (NTC) 
thermistors.
