ARM: dts: msm: Update pmic alarm thermal zone mitigation configs for GEN3

The pmic alarm sensor generates interrupt and notifies the thermal
framework only for 1st stage alarm. But thermal mitigation is enabled
only for second stage alarm for GEN3 targets. Since first trip doesn't
have mitigation, passive delay polling is also not enabled for this
zone. It leads to a case where alarm sensor reaches above second trip,
but mitigation is not applied.

Add dummy cooling map configuration for first trip threshold for these
alarm sensor thermal zones. It activates passive delay polling from
first trip violation and it will be active until it clears first
trip violation.
