qpnp-smb2: configure DRP mode after interrupt request

During hardware initialization charger is configured in
DRP mode from force UFP mode and after mode configuration
hardware takes ~300/400 msec for UFP/DFP detection. In case
if the delay between moving to DRP mode and software enabling
interrupts is more than hardware detection delay then software
will miss the detection interrupt. Fix this by moving DRP
configuration after interrupt request this ensures software will
receive interrupt once hardware detection completes.
