- Allocate the interrupt resource as RF_SHAREABLE allowing uart(4) to work
  with shared IRQs in case the bus code, MD interrupt code, etc. permits.
  Together with sys/sparc64/sparc64/intr_machdep.c rev. 1.21 (MFC'ed in
  rev. 1.19.2.1) this fixes an endless loop in uart_intr() when using the
  second NS16550 on the ISA bus of sparc64 machines.
- Destroy the hardware mutex on detach and in case attaching fails.
