The original property had three problems: its name was misspelled, the key and value order was reversed, and it described a 100 MHz clock, which does not match the device model. The property can be removed directly because the UART model's input clock matches the Linux 8250 PnP driver default of 1,843,200 Hz, so no _DSD override is needed.
