thermal: qcom: spmi-temp-alarm: Disable INT in shutdown cb

Browse Source 
On SKUs with MSM + Co-proc there can be possiblity that
because of Interrupts enabled from MSM side (SPMI) the exit
of LPM might not work because PBS gets locked because of
which the sequence to exit LPM might not get triggered.

Add support for shutdown callback and disable INT in shutdown
cb to ensure that INT are disabled before entering LPM.
