counter: microchip-tcb-capture: Allow shared IRQ for multi-channel TCBs

Mark the interrupt as IRQF_SHARED to permit multiple counter channels to
share the same TCB IRQ line.

Each Timer/Counter Block (TCB) instance shares a single IRQ line among its
three internal channels. When multiple counter channels (e.g., counter@0
and counter@1) within the same TCB are enabled, the second call to
devm_request_irq() fails because the IRQ line is already requested by the
first channel.
