[ Upstream commit 2dee50ab9e72a3cae75b65e5934c8dd3e9bf01bc ] There are two UART clock groups, each having a mux to select its upstream clock source. The register/bit definitions for accessing these two muxes appear to have been reversed since introduction. Correct them so as to match the hardware manual.
