recipes-security: optee: Remove software PRNG for am62pxx
With the latest TIFS fix [1], AM62P is able to leverage the hardware-TRNG
instead of having to fallback into the software-PRNG.
Background:
The default priv-id for A53 cores in SYSFW for AM62P was chosen to be 4
while the other K3 SOCs were configured at 1. Any firewall TISCI API
call that used 1 would not be able to run on AM62P. The TIFS fix changes
the AM62P value from 4 to 1.
