x86: edison: Switch to ACPI mode

SFI is quite poor and useless resource provider. Moreover it makes hard
to develop and extend functionality in the Linux kernel.

Enable a necessary minimum to use ACPI on Intel Edison.

Linux kernel have been prepared for this change since v5.4, where the last
crucial driver, i.e. for Basin Cove PMIC, has been submitted.

Note, that stock image won't suffer by this change since it doesn't have
ACPI enabled on the kernel level.
