soc/amd/picasso: Update i2c support
Change the stoneyridge definitions into picasso. The named 0 and 1 buses are controlled by the PSP and not directly accessible by host firmware. I2C4 operates only in slave mode so is not added to to the bus clear-after-reset sequence. The I2C controller is fundamentally the same as on Stoney Ridge so the ability to clear a potentially jammed bus is still required. Program Picasso's new pad control registers in the MISC AcpiMmio space according to the recommended settings.
