drivers: entropy: PSA crypto RNG driver default

Browse source 
Enable the PSA RNG driver by default. This option
will only be enabled when BUILD_WITH_TFM is enabled
and a device with the required compatible field
(zephyr,psa-crypto-rng) is defined in the device tree.
When a vendor includes such a device and enables the
ENTROPY_GENERATOR subsystem it is fair to assume
that wants to use the PSA Crypto RNG driver.
