soc/amd/stoneyridge: Remove double defined GPIO MMIO bases
GPIO control a mux base addresses are defined within MMIO definitions and again bellow as GPIO specific base addresses. Eliminate those outside MMIO bases. Rename them to something indicating that they are both MMIO and related to GPIO. BUG=b:117754420 TEST=Build grunt.
