Pull up following revision(s) (requested by riastradh in ticket #1490):

        sys/dev/acpi/thinkpad_acpi.c: revision 1.48

With the recent change of the EC address space handler, we no longer get
an ACPI_INTEGER in host byte order but a byte sized buffer with little
endian data.

Extract only the low 8 bits from buffer to get the fan speed again.
