boards: thingy91x: fix swapped blue/green LEDs

[szczys]

The mapping for blue and green LEDs has been swapped for both leds and pwmleds nodes to correctly control the desired color.

Issue

From the LED table on the Thingy91x hardware documentation we expect the following LED mappings:

However we can see from the current board mapping that blue and green are reversed.

sdk-nrf/boards/nordic/thingy91x/thingy91x_nrf9151_common.dts

Lines 29 to 43 in 84ec4da

	leds {
	compatible = "gpio-leds";
	red_led: led_1 {
	gpios = <&gpio0 29 0>;
	label = "RGB red channel";
	};
	green_led: led_2 {
	gpios = <&gpio0 30 0>;
	label = "RGB green channel";
	};
	blue_led: led_3 {
	gpios = <&gpio0 31 0>;
	label = "RGB blue channel";
	};
	};

Reproducing the issue

➜ git rev-parse HEAD
84ec4da2bfb18ecc3a6adffb4ae67cb520634e04

Verify that the blue and green LEDs are reversed by running the zephyr/samples/basic/blinky application with the following patch:

Correcting pwmleds

I could not find any documentation on the hardware page or in the available schematic for how the PWM channels should be mapped. However, when comparing the Thingy91 to the Thingy91x, pwmleds for green and blue are swapped in the same way described above. This PR also corrects this.

It seems you are not a member of the nrfconnect GitHub organization. External contributions are handled as follows:
Large contributions, affecting multiple subsystems for example, may be rejected if they are complex, may introduce regressions due to lack of test coverage, or if they are not consistent with the architecture of nRF Connect SDK.
PRs will be run in our continuous integration (CI) test system.
If CI passes, PRs will be tagged for review and merged on successful completion of review. You may be asked to make some modifications to your contribution during review.
If CI fails, PRs may be rejected or may be tagged for review and rework.
PRs that become outdated due to other changes in the repository may be rejected or rework requested.
External contributions will be prioritized for review based on the relevance to current development efforts in nRF Connect SDK. Bug fix PRs will be prioritized.
