drivers: nrf: Enable nRF drivers by default in Kconfig

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).
