Takashi Yano 3b39aebf98 Fix mach64 driver crash 
Due to lack of iopl(3), mach64 driver crashes when ior(BUS_CNTL) is
called. Since BUS_CNTL is out of the range 0x0000-0x03ff, ioperm(0,
1024, 1) is not sufficient and the ior() causes access violation.
This patch reintroduce iopl(3) call in the function hwEnableIO().

Addresses: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1110521
Fixes: a0f738a673 ("Fixed ioperm calls in hwEnableIO")
