hwmon: (pmbus_core) Allow to hook PMBUS_SMBALERT_MASK

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2101915

[ Upstream commit 9c6df63a66c1fdf99d6e1ad278d140080c724120 ]

Use _pmbus_write_word_data to allow intercepting writes to
PMBUS_SMBALERT_MASK in the custom chip specific code.

This is required for MP2971/MP2973 which doesn't follow the
PMBUS specification for PMBUS_SMBALERT_MASK.
