This PR performs a few cleanup actions for the build-all sensor driver
test:
1. Remove many non-sensors from the test's device tree, including
wireless radios, LED strips, flash memory, and displays. These
devices don't belong in this test and in most cases were not being
compiled anyways due to missing config flags and not being
status-okay.
2. For the remaining devices, enable them in the device tree so the
sensors build and get instantiated. A handful of device nodes that
caused linker errors due to the driver not instantiating are left
disabled.
3. Convert the test I2C and SPI buses into emulated buses to support
upcoming live testing over these sensor devices.
