[PATCH] arm64: dts: ti: k3-am62a7-sk: fix pinmux for main_uart1

[Bryan Brattlof]

From: Hong Guan <hguan at ti.com>

The &main_uart1, which is reserved for TIFS firmware traces, is routed
to the onboard FT4232 via a FET swich which is connected to pin A21 and
B21 of the SoC and not E17 and C17. Fix it.
