Make the following nRF peripheral drivers:
- ADC
- GPIO
- I2C
- SPI
- UART
- USB_DEVICE
enabled by default so that users do not need to explicitly enable them
in their applications after choosing an nRF SoC as the build target.
Kconfig options enabling these drivers depend on both a given hardware
feature (e.g. I2C) and an nRF family SoC selected, so effectively they
will be automatically enabled only when it is adequate (and in most
cases these drivers are the only option for a given hardware feature
on nRF SoCs).

This commit adds translation layers to make nrfx drivers for the nRF
ADC (nRF51 series) and SAADC (nRF52 series) peripherals accessible via
the Zephyr's API. The SAADC peripheral is accessed using nrfx HAL only
as it turns out that usage of the nrfx driver in this case would be
inconvenient and would unnecessarily complicate the shim.
