[PATCH] dt-bindings: mfd: Allow MT6360 interrupt flags

MT6360 interrupt controllers use either one interrupt cell or two
cells, with the optional second cell carrying trigger flags. Allow both
forms.

dt-bindings: mfd: Allow MT6360 interrupt flags

This commit updates the MT6360 device tree binding to allow the interrupt
controller to use either one or two cells. It replaces the constant cell
count constraint with an enum to support an optional second cell for
trigger flags.

[Severity: Medium]
Does this change conflict with the device tree binding subsystem rules? 

The subsystem guidelines mandate that cell-count properties like
#interrupt-cells must use a const constraint rather than an enum to prevent
ambiguous or variable cell sizes during schema validation.

No.

There's always exceptions to guidelines...
