leds: qpnp-flash: Add support to query maximum current 



Currently, MAX_CURRENT option is used to query the maximum
available current which is a relative value based on the battery
parameters. Rename it to MAX_AVAIL_CURRENT so that MAX_CURRENT
option can be used to query the maximum current that is supported
for flash LED devices.
