[PATCH] platform/x86: hp-wmi: Add board 8E41 (OMEN Transcend 14) to feature board list

[sjunhyuk1]

The HP OMEN Transcend 14-fb1xxx (DMI board name "8E41") is recognized
as an Omen board by omen_thermal_profile_boards[] (so platform_profile
switching works via the generic path), but it has no entry in
hp_wmi_feature_boards[]. As a result active_board_params stays NULL
for this board, is_victus_s_board is never set, and none of the
board-specific paths that depend on a real ModelCapabilities entry
(EC thermal-profile readback, the Victus-S GPU CTGP/PPAB WMI calls,
the AC/battery power-source re-apply handler) ever run for it.

Confirmed by direct EC readback (CONFIG_ACPI_EC_DEBUGFS, reading
/sys/kernel/debug/ec/ec0/io) while cycling /sys/firmware/acpi/
platform_profile through performance/balanced/cool:

    profile         offset 0x95
    performance     0x31
    balanced        0x30
    cool            0x50

These values are an exact match for hp_thermal_profile_omen_v1's
HP_OMEN_V1_THERMAL_PROFILE_PERFORMANCE (0x31), _DEFAULT (0x30) and
_COOL (0x50), read back at exactly HP_OMEN_EC_THERMAL_PROFILE_OFFSET
(0x95) -- the ec_tp_offset already used by omen_v1_legacy_board_params,
and identical to sibling boards already in the table (8902, 8A44,
8A4D, 8D26, 8E35). Two other candidate offsets from the same struct
(0x59, 0x62) were also probed and did not change with the profile;
0x63 changed by +/-1 opportunistically across reads and looks like
the unrelated timer byte, not a profile encoding.

System tested on:
  DMI board_name:   8E41
  DMI product_name: OMEN Transcend Gaming Laptop 14-fb1xxx
  BIOS version:     F.05
  Kernel:           7.1.9-arch1-2
