bankd: Implement card reset based on clientSlotStatusInd
If a client is sending us a clientSlotStatusInd indicating that
the modem has switched off VCC or activated RST, bankd will
now issue a respective PC/SC command to perform a cold or warm
reset of the card.
Change-Id: Ifa615d239ec3ad6daebd8e99e4f7d5b99d32c0e1
Closes: OS#4330
