[PATCH 2/4] platform/x86: hp-wmi: Add support for OMEN MAX 16-ak0xxx (8D87)

[Krishna Chomal <krishna.chomal108@gmail.com>]

The HP OMEN MAX 16-ak0xxx (8D87) requires the same WMI queries as other
Victus S devices, hence it has been added to the corresponding list.

For this reason, platform_profile_victus_s_get_ec() will be called
during thermal_profile_setup() and victus_s_powersource_event() to
obtain hardware state (platform profile) by reading from the Embedded
Controller, however, this particular board's EC does not seem to expose
the platform profile value, unlike other boards. Hence EC readback is
disabled.

Testing on board 8D87 confirmed that platform profile is registered
successfully and fan RPMs are readable and controllable.
