[PATCH] doc: board: fix OPTEE args for TI SoCs

[PATCH] doc: board: fix OPTEE args for TI SoCs

[Anshul Dalal]

CFG_WITH_SOFTWARE_PRNG=y was added as an OPTEE argument to workaround
some bugs related to TRNG which have been fixed now[1]. Therefore this
patch drops the redundant argument from the documentation.
