soc: qcom: rpmh-rsc: Unconditionally clear _TRIGGER bit for TCS

Unconditionally clear the TCS_AMC_MODE_TRIGGER bit when a
transaction completes. Previously this bit was only cleared when
a wake TCS was borrowed as an AMC TCS but not for dedicated
AMC TCS. Leaving this bit set for AMC TCS and entering deeper low
power modes can generate a false completion IRQ.

Prevent this scenario by always clearing the TCS_AMC_MODE_TRIGGER
bit upon receiving a completion IRQ.
