gpio: bcm_kona: rename confusing variables

Browse Source 
Rename the argument "virq" to just "irq", this IRQ isn't any
more "virtual" than any other Linux IRQ number, we use "hwirq"
for the actual hw-numbers, "virq" is just bogus. Rename the
"gpio" variable to "hwirq" to reflect what it is. Rename one
instance of "virq" to "child_irq" that better describes what
it is.
