nrf54l15dk: Failing to build with CONFIG_ENTROPY_GENERATOR

[rettichschnidi]

Describe the bug

Building for nrf54l15dk fails when enabling Bluetooth and entropy drivers at the same time.

To Reproduce

1. west build --pristine --board nrf54l15dk/nrf54l15/cpuapp zephyr/samples/hello_world/ -- -DCONFIG_BT=y -DCONFIG_ENTROPY_GENERATOR=y

Expected behavior

Build should work. As it does e.g. for the nrf52840dk: west build --pristine --board nrf52840dk/nrf52840 zephyr/samples/hello_world/ -- -DCONFIG_BT=y -DCONFIG_ENTROPY_GENERATOR=y

Impact

Need to chose between BT and ENTROPY_GENERATOR.

[cvinayak]

There is no supported entropy driver for nRF54L15 yet in the upstream Zephyr Project.
When there is one, it will need to support its APIs being invoked from thread and ISR execution contexts, and change the code in link layer to use a DTS choosen entropy device.
