    driver: add Apple SMC driver ported from FreeBSD asmc
    
    Port of the FreeBSD asmc(4) driver to DragonFlyBSD with the following
    adaptations:
    - kmalloc/kfree instead of malloc/free
    - ksnprintf instead of snprintf
    - lockmgr() 2-arg form (no whandle)
    - taskqueue_start_threads() with ncpu=-1 arg
    - sys/bus_resource.h instead of machine/resource.h
    - contrib/dev/acpica paths for acpi.h/accommon.h
    - u_long instead of rman_res_t
    
    Driver layout: sys/dev/apple/smc/
      smc.c      - probe/attach/detach, module glue
      smc_io.c   - ISA port I/O backend
      smc_mmio.c - MMIO/T2 backend
      smc_sysctl.c - sysctl handlers for fans, temps, SMS, light sensors
      smc.h      - shared types, macros, prototypes
