Its been reported that some kernel versions still need the XHCI reload while others only work if the reload isn't present. Lets give the user the ability to control that for DT systems.
Further, there is now an example persistent variable store implementation that uses the on-board SPI flash rather than trying to rewrite the UEFI firmware image on SD/etc late in the boot cycle. The problem is that we now need to control the GPIO pin mux. This isn't a problem for Linux as such, because it only messes with the pin mux under DT, but windows has some drivers which export the GPIO devices using the ACPI definition. Lets add a menu item to enable the GPIO and default it to off on the RPi4 under the assumption that we can't fix a GPIO pin mux war reliably and instead will simply revert to a mode that fails to persist variables written while the OS is active if the GPIO is enabled. This set also cleans up the ACPI/DT visiblity of a couple nearby menu items as well.
