[PATCH] gpio: tc3589x: drop references to "virtual" IRQ

[PATCH] gpio: tc3589x: drop references to "virtual" IRQ

[Linus Walleij]

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.
