clk: renesas: r9a06g032: Fix UART clkgrp bitsel

[ 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.
