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.
