soc: qcom: sysmon: Increase the shutdown indication timeout

Currently, after sending a shutdown request to the
SSCTL v2 service on the subsystem, the sysmon-qmi
driver waits for 5 seconds to receive an indication
before it returns an error and proceeds with powering
down the subsystem. This timeout is not adequate in
all cases since sometimes, the modem shutdown/cleanup
can take up to 10 seconds. Increase the sysmon driver
timeout to match that.
