Re-add support for Aries Embedded MCV SoM, which is CycloneV based
and the associated MCVEVK and MCVEVP baseboard. The board can boot
from eMMC. Ethernet and USB is supported.

The Aries Embedded boards have been removed with commit 03b54997
("board/aries: Remove"). I will now take care of them.

The device-tree files are from mainline Linux commit e93c9c99a629
("Linux v5.1)".

The stratix 10 reset manager ad-hoc code in arch/arm contains an unused
function 'reset_deassert_peripherals_handoff' that has been added from
the beginning. As this is probably a result of copying the gen5 reset
manager and this function has never been used, remove it.

commit c5de2b7e ("arm: socfpga: implement proper peripheral reset")
has removed the call to 'reset_deassert_peripherals_handoff()' from
socfpga gen5 SPL since the reset driver now handles resets. However,
commit c1d4b464 ("ARM: socfpga: Disable bridges in SPL unless booting from FPGA")
has re-added this ad-hoc reset code, so that all peripherals were now
again enabled instead of letting the drivers enable them by request.

While at it, remove this function for gen5 as it should not be used.

Pull request for UEFI sub-system for v2019.07-rc3

The development target for the UEFI sub-system is EBBR compliance. We have
already implemented some further protocols to enable running the UEFI Shell
and the UEFI SCT test suite.

As some boards are severely memory constrained make some of these extras
customizable.

Provide bug fixes. The most prominent ones let us pass the UEFI SCT memory
allocation tests.

- A10 FPGA programming support, Gen5 livetree conversion

- SH2, SH3 removal

Describe that efi_install_fdt() defaults to using the device tree
indicated by environment variable fdtcontroladdr.

ACPI tables and device trees are mutually exclusive.

The device path to text protocol renders ACPI device nodes incorrectly.

Use capital hexadecimal numbers as shown in the UEFI spec examples.

Always output the optional UID. This matches what UEFI SCT expects and
saves us an `if`.

UEFI SCT uses this call sequence to determine the current TPL level inside
notification functions:

    OldTpl = BS->RaiseTPL(TPL_HIGH_LEVEL);
    BS->RestoreTPL(OldTpl);

In RestoreTPL() we trigger the notification function of queued events. If
we do not mark the event as non-queued before calling the notification
function, this results in an infinite recursive call sequence.

Mark the event as non-queued before entering the notification function.

If AllocatePages() is called with AllocateAddress, the UEFI spec requires

The UEFI SCT II 2017 spec additionally requires to return EFI_NOT_FOUND if

When we call FreePages() we essentially add memory to our memory map. We
shouldn't do this for memory that does not exit.

Check if the memory that is to be freed via FreePages() or FreePool() is in
our memory map and is not EFI_CONVENTIONAL_MEMORY.

This check is mandated by the UEFI specification.
