The attn IRQ is related to the chip, rather than the transport, so move
all handling of interrupts to the core driver. This also makes sure that
there are no races between interrupts and availability of the resources
used by the core driver.

Instantiating the rmi4 I2C transport driver without interrupts assigned
(for example using manual i2c instantiation from the command line)
caused the driver to fail to load, but it does not clean up its regulator
or transport device registrations. Result is a crash at a later time,
for example when rebooting the system.
