sparc32 do not clear interrupts when masking
Don't clear interrupts on disabling, because
* Sun4M_SystemArchitecture_edited2.pdf doesn't describe
that masking or un-masking IRQ shall clear pending ones.
* Field tests also show that SPARCstation-20 doesn't
clear them.
* The patch makes Solaris 2.5.1/2.6 boot ~1500 times
faster (~20 seconds instead of ~8 hours)
