soc/amd/stoneyridge/lpc.c: Fix bit definitions
The latest public BKDG (3.6) releases some previously undefined (reserved)
bits, also some bits were wrongly named (possibly copied from previous chip).
Fix these definitions, including the header file where they are defined.
BUG=b:77940747
TEST=Build and boot grunt.
