Add P-states for select Socket 754 processors.
States for AMA3000BEX5AR, SDA3100AIO3BX, and SDA3400AIO3BX are from AMD document 30430 3.51. States for ADA3200AIO4BX derived from SSDT of a MS-7135. States for TMDML34BKX5LD derived from legacy PowerNow! table of a MS-7135, and therefore lack accurate TDP information.
