Subject: [PATCH] mfd: intel-lpss: Add support for MacBookPro16,2 UART

The MacBookPro16,2 has a UART controller with pci id 8086:38a8. Added
this device to the intel_lpss_pci driver. This allows access to its
Bluetooth controller.

The name of this device is not known, however as it appears to only be
found on the one model (MacBookPro16,2), labelling it with that
model's name should be sufficient to identify it. (Unless some folks
from Intel know what to call it and what its section should be called.)

Records here indicate that this device is only present on the one model:
https://linux-hardware.org/?id=pci:8086-38a8-8086-7270
