max8925_power: No temperature interrupts if temperature not connected
Brownstone does not have temperature reading circuit hooked up. This leads to spurious interrupts. Allow the platform layer to indicate no temperature circuit and do not activate interrupts if no temperature control is set Signed-off-by: Philip Rakity <prakity@marvell.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
