ASoC: wcd9335: Disable irq on slave ports in the remove function
The probe calls 'wcd9335_setup_irqs()' to enable interrupts on all slave
ports.
This must be undone in the remove function.
Add a 'wcd9335_teardown_irqs()' function that undoes 'wcd9335_setup_irqs()'
function, and call it from the remove function.
