ig4: Add support for Lunar Lake-M I2C
this patch adds PCI IDs to the ig4(4) driver:
- Lunar Lake-M (0xa878, 0xa879, 0xa87a, 0xa87b)
These controllers use the Tiger Lake hardware revision of the I2C IP.
Adding these IDs enables support for peripherals connected to the I2C Bus.
Tested on: Intel Lunar Lake (LENOVO_MT_21QX_BU_Think_FM_ThinkPad T14s Gen 6)
