configs/microchip_sama7g5ek_mmc_dev_defconfig: add rng tools
Add rng tools. Without this, when booting, prompt will not
appear until 'random: crng init done' appears.
Avoid this by using rng tools without the libjitterentropy.
Libjitterentropy is a jitter source of entropy which does
not help for AT91 cpus as the jitter does not have
enough variance to generate fast enough entropy.
