bmm350: Add Streaming and Read-Decode support

[ubieda]

Description

This PR introduces Read-Decode and Streaming mode support to the existing BMM350 driver in-tree.
To accomplish this, there was some refactoring done to allow both v1 and v2 model to coexist without unnecessary code duplication.

Testing

Ran Sensor Shell with BMM350 enabled on an MCXN947 FRDM board and verify both v2 model (read-decode and streaming mode) as well as v1 model (fetch-get) work.

• Build command (Streaming enabled):

west build -b frdm_mcxn947/mcxn947/cpu0 samples/subsys/shell/shell_module -- -DCONFIG_SENSOR=y -DCONFIG_SENSOR_SHELL=y -DCONFIG_SENSOR_SHELL_STREAM=y

• Overlay frdm_mcxn947_mcxn947_cpu0.overlay

&flexcomm2_lpi2c2 {
	status = "okay";
	
	bmm350:bmm350@14 {
		compatible = "bosch,bmm350";
		reg = <0x14>;
		status = "okay";
		odr = "3.125";

		/* Arduino pin: D2 */
		drdy-gpios = <&gpio0 29 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>;
		push-pull-int;
		active-high-int;
	};
};

• Console Output:

I'd like to highlight these two APIs, which could end up in the regmap.h file @avisconti has created in his in-flight PR.
