[PATCH 7/8] arm64: dts: imx93-kontron: Fix UART RTS/CTS pad names

[Frieder Schrempf]

From: Frieder Schrempf <frieder.schrempf at kontron.de>

On i.MX93 the LPUART RTS_B signal is an output and CTS_B is an input,
so they connect directly to the OSM-S UART_x_RTS and UART_x_CTS pads.
The naming used for the Gpio labels and pinmux comments was carried
over from i.MX8M, where the UART RTS/CTS signals have the opposite
direction.

Fix the naming to match the hardware:

  GPIO_IO06 (LPUART6_CTS_B) -> UART_B_CTS
  GPIO_IO07 (LPUART6_RTS_B) -> UART_B_RTS
  GPIO_IO10 (LPUART7_CTS_B) -> UART_A_CTS
  GPIO_IO11 (LPUART7_RTS_B) -> UART_A_RTS

Fixes: 2b52fd6035b7 ("arm64: dts: Add support for Kontron i.MX93 OSM-S SoM and BL carrier board")
