2019-06-06soc/amd/stoneyridge: Move LPC support to commonMarshall Dawson
AMD devices traditionally have the LPC-ISA bus at 14.3 and the definition has been very consistent. Relocate the feature from stoneyridge into common/block.

2019-06-06soc/amd/stoneyridge: Rework SPI base address get/setMarshall Dawson
A subsequent patch will move the soc//stoneyridge LPC functionality to a common directory. Prepare by reworking the SPI BAR configuration function in southbridge.h. The SPI BAR is not a typical PCI BAR, and is at D14F3xA0.

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.

2019-05-06soc/amd/stoneyridge: Correct bugs in lpc.cMarshall Dawson
Remove the bridge enable step of accessing D14F0x64. This method for enabling the bridge appears to be last present in the SB700 device. Beginning in the SB800 (and all FCH, SoC devices), the enable is in PMxEC[0]. Since the bridge is enabled in bootblock to allow port 80h, there is no need to maintain it in ramstage. Correct the device used for misc. configuration of the LPC bridge. The #defined value removed is 14.0 but the settings are in 14.3.

When building grunt with flags set to detect variables that get a value but then are unused, there are 5 instances that causes error (unused variable). In most cases it's enough to simply remove the variable. Other instances, is better to simply use the variables (one instance it's a return value, on the other instance using the variables makes code more readable).
