  Log:
  MFC: 1.13
  
  - 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.
