[PATCH 2/6] counter: 104-quad-8: Ensure number of irq matches number of base

[William Breathitt Gray]

The 104-quad-8 module calls devm_request_irq() for each device. If the
number of irq passed to the module does not match the number of base, a
default value of 0 is passed to devm_request_irq(). IRQ 0 is probably
not what the user wants, so utilize the module_isa_driver_with_irq macro
to ensure the number of irq matches the number of base.
