drivers: entropy_nrf5: Use device name and IRQ priority from DTS

Browse source 
Instead of using Kconfig options for setting the device name and IRQ
priority for the entropy_nrf5 driver, get these settings from the rng
node defined in DTS for a given SoC.

Provide also fixups for CONFIG_ENTROPY_NAME, until applications using
entropy drivers are converted to use DTS as well.
