hwmon: applesmc: prolong status wait

The time to wait for a status change while reading or writing to the SMC
ports is a balance between read reliability and system performance.  The
current setting yields rougly three errors in a thousand when
simultaneously reading three different temperature values on a Macbook
Air.  This patch increases the setting to a value yielding roughly one
error in ten thousand, with no noticable system performance degradation.
