drivers/rng: simplify Kconfig
For all sandbox systems with DM_RNG we enable RNG_SANDBOX. So we can simply
set the default to yes.
All rng drivers depend on DM_RNG. Use a single 'if' instead of individual
dependencies. Now 'make menuconfig' shows the individual drivers neatly
indented under the DM_RNG entry.
