[PATCH] hwclock: define cmos_interface only if necessary

[PATCH] hwclock: define cmos_interface only if necessary

[unixmania]

From: Carlos Santos <unixmania@gmail.com>

Move the static declaration to the probe_for_cmos_clock() function and
make it conditional to i386/x86_64, preventing a "defined but not used"
compiler warning.
