drivers: mark first batch of compilable drivers for COMPILE_TEST ...

All of these drivers have a runtime dependency on SoC peripherals, but
can nevertheless be compile-tested. Add COMPILE_TEST as an alternate
dependency.

bus: efi: add basic ACPI bus infrastructure ...

It makes sense to support some ACPI tables like the WDAT (Watchdog
Action Table) in barebox. To facilitate this add a ACPI bus and
the necessary bits to integrate ACPI tables into the barebox
device/driver model as devices. These devices are identified by the
four byte signature, which drivers can then match against and the
system description table (SDT) of the device is then available as a
device memory resource.

Even without drivers, with this patch, devinfo and md can now be used
to view the ACPI system description tables, which can be useful
during UEFI payload development.

Support for the ACPI Machine Language and ACPI 5.1 _DSD (Device
Specific Data) is not implemented.

drivers: bus: Add ti-sysc bus driver ...

Adds minimal support for the sysc interconnect target module found
on many TI SoCs. With this device tree includes have been rearagned.
We need the driver to probe the child devices of the bus.

bus: mvebu: add mbus driver ...

This imports the Marvell mbus driver from Linux. The mbus is the
main downstream bus found on all Marvell Orion SoCs. The driver
deals with re-configurable address windows which are currently
parsed from DT. Also enable the driver as default on all MVEBU
SoCs. While at it, also reorder drivers/bus/{Kconfig,Makefile}
alphabetically.

bus: Add omap gpmc driver ...

This adds a devicetree-only driver for to configure the gpmc and its
child devices from dt. Currently only NAND is supported.

bus: Add imx-weim support ...

Mostly taken from the kernel with support for other SoCs from
Alexander Shiyan.
