Kumar Gala df81fef944 drivers: sensor: Convert Kconfig bus 'depends on' to 'select'
This change in pattern is meant to address a misconfiguration issue
that can occur for sensors that support being on multiple busses
like I2C & SPI.

For example, you can have a configuration in which such a sensor is
on the I2C bus in the devicetree and the sensor is enabled.  However
the application configuration enables CONFIG_SPI=y and CONFIG_I2C=n
and this will cause the sensor driver to be built by default, however
since we don't have the I2C bus enabled the driver will not compile
correctly.

Previously we had been adding to board Kconfig.defconfig something
like:

	config I2C
		default y if SENSOR

This pattern doesn't scale well and may differ from what an application
specific need/use is.

So instead move to a pattern in which we leave the default enablement
up to the devicetree "status" property for the sensor.  We then have
the Kconfig move from 'depends on <BUS>' to 'select <BUS>' and in
the case of drivers that support multiple busses we have the Kconfig
be: 'select <BUS> if $(dt_compat_on_bus,$(<DT_COMPAT>),<BUS>) for
each bus type the sensor supports.

This removes the need to add Kconfig logic to each board and enables
the bus subsystem and bus controller driver if the sensor requires
it by default in the build system.

Fixes: #48518
