Subject: [RFCv2,1/2] v4l2-controls.h: add addtional Flash fault bits 

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.
