[PATCH] hwmon: (core) Add missing beep-related standard attributes

[James Seo <james@equiv.tech>]

beep_enable, inX_beep, currX_beep, fanX_beep, and tempX_beep
are standard attributes mentioned in the sysfs interface
specification but not implemented in the hwmon core. Since
these are not deprecated, implement them.

Adding beep_mask is not necessary, as it is deprecated and
the drivers already using it are manually defining it.
