hwrng: amd - remove reference to removed PPC_MAPLE config

Commit 62f8f30 ("powerpc/64: Remove maple platform") removes the
PPC_MAPLE config as a consequence of the platform’s removal.

The config definition of HW_RANDOM_AMD refers to this removed config option
in its dependencies.

Remove the reference to the removed config option.
