irqchip/realtek-rtl: Map control data to virq

BugLink: https://bugs.launchpad.net/bugs/1959879
commit 291e79c7e2eb6fdc016453597b78482e06199d0f upstream.

The driver assigned the irqchip and irq handler to the hardware irq,
instead of the virq. This is incorrect, and only worked because these
irq numbers happened to be the same on the devices used for testing the
original driver.
