Pull up following revision(s) (requested by jdolecek in ticket #959):

        sys/dev/acpi/acpi_ec.c: revision 1.84

only install space handler and enable interrupt for EC if ACPI

claims the device is actually present, it's not enough when there
is entry for it in the ACPI tables
fixes interrupt storm triggered on Dell PowerEdge R220 by enabling
GPE interrupt on a non-enabled EC (for which _REG call later
fails), reported and fix tested by Dima Veselov:
