serial: 8250_dw: Add device HID for new AMD UART controller
Browse files Browse the repository at this point in the history
commit 3c35d2a upstream.

Add device HID AMDI0022 to the AMD UART controller driver match table
and create a platform device for it. This controller can be found on
Microsoft Surface Laptop 4 devices and seems similar enough that we can
just copy the existing AMDI0020 entries.
