platform/x86: hp-wmi: Add support for HP Laptop 15-fd1xxx (board 8DE1)
On the HP Laptop 15-fd1xxx (motherboard ID 8DE1), hp-wmi currently falls
back to the legacy HPWMI_FAN_SPEED_GET_QUERY (0x11) command because the
board is not listed in hp_wmi_feature_boards[].
In HP BIOS DSDT table (e.g. BIOS F.26), method GM11 (query 0x11) is a
dummy stub that returns 4 bytes of 0x00 with return code 0 (success),
causing the driver to report 0 RPM via hwmon even while the fan is
actively spinning.
However, the DSDT implements method GM2D (query 0x2D / Victus S fan
interface), which reads the active fan tachometer directly from the
Embedded Controller (EC0) registers RPM1/RPM2 and reports accurate fan
speed.
Add board ID "8DE1" to hp_wmi_feature_boards[] mapped to
victus_s_board_params so hp-wmi uses the working query 0x2D interface.
