vendorcode/intel: allow selecting EDK headers manually

EFI-specific options depend on CONFIG_UDK_BASE which gets set only when
CONFIG_*_BINDING is selected by SOCs (e.g., when necessary for Intel
FSP).  This prevents enabling DRIVERS_EFI_VARIABLE_STORE and
DRIVERS_EFI_FW_INFO options for boards which don't require EDK bindings
for anything else.

Make version of the bindings freely selectable when SOC doesn't request
a specific version and EDK2 payload is used.

The implementation looks somewhat ugly and duplicated because otherwise
kconfig detects a loop in configuration options and refuses to do
anything.
