gpio: pcf857x: Fix interrupts on multiple instances
When multiple instances of pcf857x chips are present, a fix up
message [1] is printed during the probe of the 2nd and later
instances.
The issue is that the driver is using the same irq_chip data
structure between multiple instances.
Fix this by allocating the irq_chip data structure per instance.
[1] fix up message addressed by this patch
[ 1.212100] gpio gpiochip9: (pcf8575): detected irqchip that is shared with multiple gpiochips: please fix the driver.
