Enable or disable the power button in Kconfig
Some mainboards need to disable the power button to avoid turning off right after being turned on, while other boards ship with a jumper over the power button and should allow the user to configure the behavior. This adds infrastructure in the form of four mutually exclusive options which can be selected in a mainboard Kconfig (power button forced on/off, and user-controllable with default on/off) and one result bool which source code can test. (Enable the button or not.) The options have been implemented in CS5536 code and for all mainboards which select SOUTHBRIDGE_AMD_CS5536, but should be used also by other chipsets where applicable. Note that if chipset code uses the result bool ENABLE_POWER_BUTTON, then every board using that chipset must select one out of the four control options in order to build. All touched boards should have unchanged behavior, except pcengines/alix1c, traverse/geos and lippert/hurricane-lx where the power button can now be configured by the user. Build tested for alix1c, alix2d, hurricane-lx and wyse-s50. Confirmed to work as advertised on alix1c both with button enabled and disabled. Includes additional traverse/geos changes from Nathan and lippert/hurricane-lx changes from Jens to correctly use the new feature on those boards.

+ The selected mainboard can optionally have the power button tied
