[PATCH v8 2/5] Bluetooth: btmtksdio: Pass hardware dev_id to mt79xx_setup()

[Chris Lu <chris.lu@mediatek.com>]

Pass the device ID read from hardware register (0x70010200) to
mt79xx_setup() instead of hardcoded 0, ensuring SDIO devices display
the correct chip ID in firmware logs.

This matches the USB driver behavior which reads from the same hardware
register. The hardware register is the authoritative source for chip
identification, superior to using the static chipid from device table.
