[SPARC64]: Fix SBUS IRQ regression caused by PCI-E driver.
We used to access the 64-bit IRQ IMAP and ICLR registers of bus
controllers 4-bytes in and as a 32-bit register word, since only the
low 32-bits were relevant. This seemed like a good idea at the time.
But the PCI-E controller requires full 8-byte 64-bit access to
these registers, so we switched over to accessing them fully.
SBUS was not adjusted properly, which broke interrupts completely.
