ASoC: cs43130: Allow driver to work without IRQ connection

Browse source

Add a polling mechanism that will keep the driver operational even in
absence of physical IRQ connection. If IRQ line is detected, the driver
will continue working as usual, in case of missing IRQ line it will
fallback to the polling mechanism introduced in this change.
This will support users which choose not to connect an IRQ line as it
is not critical to part's operation.
