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.

net: remove unused Kconfig options ...

Both options are used nowhere and can be dropped:

- OF_NET code is compiled always and code is discarded at link-time if
  unreferenced
- Designware Ethernet can be enabled in Kconfig and no arch code

net: eqos: extend Designware Ethernet QoS for Tegra 186 support ...

The U-Boot dwc_eth_qos driver ported in the previous commit had support
for both the Tegra 186/194 and STM32MP variants of the EQOS IP.

The barebox Tegra supported doesn't include the 186, but as the driver
was nevertheless ported along with the rest, lets include it in the
source tree.

net: add Designware Ethernet QoS for STM32MP ...

We already have Designware NIC support in barebox, but for the DWMAC1000,
the DWMAC4 (also called GMAC4), no support was mainline so far.

The DWMAC4 is different enough that sharing code with the DWMAC1000 is
not really that helpful, because even basics like MDIO registers have
different layout. Instead of coding bit masks and shifts into the driver
data, like Linux does, we'll keep both driver kinds separate.

Nevertheless, we collect functions that are not SoC-specific into a
separate 'library' file.

treewide: replace '---help---' with 'help' in Kconfig files ...

In Linux, '---help---' was deprecated in favor of 'help', and
this is checked by the recent checkpatch.pl

See Linux commit 84af7a6

The number of '---help---' is gradually decreasing in Linux, but there
are still lots. However, '---help---' will be completely killed when
the time comes.

Fortunately, there are only some in Barebox. Replacing them is not hard.

net: Add Freescale FMan ethernet support ...

This adds ethernet support for the Freecale Layerscape SoCs. The
architecture in these SoCs is called "Data Path Acceleration
Architecture" (DPAA). It is comprised of:

- The Queue Manager (QMan)
- Buffer Manager (BMan)
- Frame Manager (FMan)
- Multirate Ethernet Media Access Controller (mEMAC)

The code is based on the corresponding U-Boot driver enriched with
device tree parsing and proper device driver support.

Tested on LS1046a, should work on other SoCs aswell with some minor
quirks. SerDes support has been removed for now.

net: Add Intel e1000 driver ...

This adds the Intel e1000 driver from U-Boot. The driver looks in parts
quite similar to the kernel driver, I don't know whether one is derived
from the other or if they both just have the same origin.

Many coding style related issues are fixed, the code is simplified in
several places. All features of the original driver should still be there,
only fiber support is disabled since it's quite unlikely that this is
used in barebox.

The driver has been tested with the i.MX6 PCIe driver and a I210 e1000
device (0x8086:0x1533)

sandbox: allow "make ARCH=sandbox allyesconfig" ...

Compiling the tree with allyesconfig is helpful because different
compilers (gcc, clang) or static checkers (e.g. clang's scan-build)
can then process and check more code.

This patch introduces two new configuration symbols that Kconfig files
can depend on. That way, code that is only working where a cache or DMA
implementation exists can be opted out.
