RHEL commit d7b246e19d4e81f231b3aff6c3885c325be9a9d2 "i386: expose
fw_cfg QEMU0002 in SSDT" modified ssdt-misc.dsl to export fw_cfg in
ACPI tables. However, the file isn't compiled in RHEL.

Use known good version acpica-tools-20150619-3.el7.x86_64 to build the
new compiled version. I verified with a RHEL5 guest that #1377087
isn't happening again after this update.

RHEL only: This is needed so kernel module can find the device and
load the driver. Upstream qemu uses different API to build ACPI
tables.
