entropy: bt_hci: driver added Adds an entropy driver that uses Bluetooth HCI commands as its source of randomness. As this method is blocking, the ISR API is not supported. As this method will range from relatively slow (same core Bluetooth HCI controller) to extremely slow (UART HCI Bluetooth controller), use the xoshiro PRNG by default for RNG generation.

drivers: entropy: Update drivers to use devicetree Kconfig symbol Update entropy drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

Bluetooth: Fix compilation for entropy_bt_hci An application with the following config fails to link on nrf53 app core: ``` CONFIG_BT=y CONFIG_BT_HCI_RAW=y CONFIG_ENTROPY_GENERATOR=y ``` This happens because `entropy_bt_hci.c` uses functions from `hci_core.c`, which is only compiled if `BT_HCI_HOST` is selected.
