So remove option to use SW TRNG by OPTEE.

just curious: Did you have to change .configs for either?

We are using the (arm64) defconfig in linux, so no.
Regarding u-boot, I don't know because we are using our own config
and I had to enable CONFIG_OPTEE there (as well as
CONFIG_OPTEE_SERVICE_DISCOVERY, but that one is default y).
