leds: leds-qti-flash: Add support for qcom,secure-vm

Browse Source 
Currently, to calculate max_avail_current, parameters from battery power
supply are needed. These parameters are provided by battery_charger driver,
which on some platforms need to be obtained from charger FW. Add a new
property "qcom,secure-vm" which if specified for a secure VM would provide
a fixed max_avail_current to support camera SW requirements.
