2019-06-06soc/amd/stoneyridge: Remove sb_util.cMarshall Dawson
Obsolete pm_acpi_pm_cnt_blk(), and remove it and pm_acpi_pm_evt_blk(). Relocate the remaining functions to get/save UMA information to southbridge.c.

Move the function into common code. Convert it to use the memory- mapped access type. Convert vboot_platform_is_resuming() to call it instead of duplicating the source.

2019-05-16soc/amd/common: Create AcpiMmio functionality from stoneyridgeMarshall Dawson
Move the stoneyridge AcpiMmio code into soc/amd/common. The SB800 southbridge introduced the MMIO hardware blocks at 0xfed80000 commonly known as AcpiMmio. Implementations beginning with Mullins enable decode in PMx04. Older designs use PMx24 and allow for configuring the base address. Future work may support the older version. Comparing the documentation for AMD's RRGs and BKDGs, it is evident that the block locations have not been reassigned across products. In some cases, address locations are deprecated and new ones consumed, e.g. the early GPIO blocks were simpler at offset 0x100 and the newer GPIO banks are now at 0x1500, 0x1600, and 0x1700. Note: Do not infer the definitions within the hardware blocks are consistent across family/model products.

2019-01-30soc/amd/stoneyridge: Access SMBUS through MMIORichard Spiegel
Currently SMBUS registers are accessed through IO, but with stoneyridge they can be accessed through MMIO. This reduces the time of execution by a tiny amount (MMIO write is faster than IO write, though MMIO read is about as fast as IO read) as most of the time consumed is actually transaction time. Convert code to MMIO access. BUG=b:117754784 TEST=Used IO to write and MMIO to read, to confirm a one to one relationship between IO and MMIO. Then build and boot grunt.
