Debug console is the part of serial driver in the same file. It means to be
able to enable debug console you also need to enable driver itself.
That's why add all dependecies and list only debug consoles which are
enabled based on driver selection to avoid compilation error when user
asks for certain debug console but driver is not enable for it.

Pull request for UEFI sub-system for efi-2020-07-rc4

This patch series addresses the following issues:

* allow compiling with clang
* add missing function descriptions to the HTML documentation
* simplify the validation of UEFI images
* validate load options in the UEFI boot manager

In a preparatory patch a structure definition is moved.

- Toshiba spinand (Yoshio)
- SPI/SPI Flash cleanup (Jagan)
- Remove SH SPI (Jagan)

- H6 emac support
- USB PHY H6 logic alignment

- Update various docs to not have 'ARCH=' in them as that's not part of
  how U-Boot builds.
- Add macOS tools-only build to Azure to help catch problems on BSD
  hosts with tools.
- Bugfixes from the latest header cleanup around ARCH_DMA_MINALIGN
- Assorted small Kconfig logic/typo corrections
- Add a default hash to FIT images that have their its auto generated.
- Other assorted fixes

The global variable, efi_guid_cert_type_pkcs7, will also be used in
efi_image_loader.c in a succeeding patch so as to correctly handle
a signature type of authenticode in signed image.

Meanwhile, it is currently defined in efi_variable.c. Once some secure
storage solution for UEFI variables is introduced, efi_variable.c may
not always be compiled in.

So move the definition to efi_signature.c as a common place.

On ARM systems gd is stored in register r9 or x18. When compiling with
clang gd is defined as a macro calling function gd_ptr(). So we can not
make assignments to gd.

In the UEFI sub-system we need to save gd when leaving to UEFI binaries and
have to restore gd when reentering U-Boot.

Define a new function set_gd() for setting gd and use it in the UEFI
sub-system.

For passing the optional data of the load option to the loaded imaged
protocol we need its size.

efi_deserialize_load_option() is changed to return the size of the optional
data.

As a by-product we get a partial validation of the load option.
Checking the length of the device path remains to be implemented.

Some Coverity defects identified the load options as user input because
get_unaligned_le32() and get_unaligned_le16() is called. But non of these
Coverity defects can be resolved without marking functions with Coverity
specific tags.
