irqchip: Switch back to struct platform_driver::remove()

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return
void") .remove() is (again) the right callback to implement for platform
drivers.

Convert all platform drivers below drivers/irqchip/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done by
just changing the structure member name in the driver initializer.
