ALSA: hda: cs35l41: Fix boost type for HP Dragonfly 13.5 inch G4
The HP Dragonfly 13.5 inch G4 (SSID 103C8B63) has _DSD properties in ACPI firmware with valid reset-gpios and cs-gpios for the four CS35L41 amplifiers on SPI. However, the _DSD specifies cirrus,boost-type as Internal (0), while the hardware requires External Boost. With Internal Boost configured, the amplifiers trigger "Amp short error" when audio is played at moderate-to-high volume, eventually shutting down entirely. Add a configuration table entry to override the boost type to External, similar to the existing workaround for 103C89C6. All GPIO indices are set to -1 since the _DSD provides valid reset-gpios and cs-gpios. Confirmed on BIOS V90 01.11.00 (January 2026), the latest available.
