Kai-Heng Feng 0edeb8992d misc: rtsx: Avoid mangling IRQ during runtime PM
After commit 5b4258f672 ("misc: rtsx: rts5249 support runtime PM"), when the
rtsx controller is runtime suspended, bring CPUs offline and back online, the
runtime resume of the controller will fail:

There's interrupt immediately raised on rtsx_pci_write_register() in
runtime resume routine, but the IRQ handler hasn't registered yet.

So we can either move rtsx_pci_write_register() after rtsx_pci_acquire_irq(),
or just stop mangling IRQ on runtime PM. Choose the latter to save some
CPU cycles.
