52cbac9b06 efi_loader: clean up UEFI sub-system initialization
allow_unaligned(), switch_to_non_secure_mode(), and efi_init_obj_list() are
called in sequence in multiple places.

Move calls to allow_unaligned() and switch_to_non_secure_mode() to
efi_init_obj_list().

Remove unused includes.

d40e05ae95 efi_loader: set OsIndicationsSupported at init
UEFI variables should be installed using well-defined API.
Currently we don't support much, but the value of OsIndicationsSupported
will be updated once some features are added in the future.

Add comments. Rename a variable.

07805f203b efi_loader: fix setting PlatformLang
The UEFI variables PlatformLang and PlatformLangCodes specify the current
firmware language and the list of all available languages.

Currently their values are hard coded. With the patch a new configuration
variable EFI_PLATFORM_LANG_CODES is provided.

When initializing the UEFI subsystem this configuration variable is used to
initialize PlatformLangCodes. The value of variable PlatformLang is read.
If it is not set, the first language specified in EFI_PLATFORM_LANG_CODES
is used to initialize PlatformLang.

e7ac009b00 efi_loader: move efi_save_gd() call to board_r.c
The first functions of the UEFI sub-system are invoked before reaching the
U-Boot shell, e.g. efi_set_bootdev(), efi_dp_from_name(),
efi_dp_from_file(). We should be able to print out device paths for
debugging purposes here.

When printing device paths via printf("%pD\n", dp) this invokes functions
defined as EFIAPI. So efi_save_gd() must be called beforehand.

So let's move the efi_save_gd() call to function initr_reloc_global_data(()
in board_r.c.

734d3252af efi_loader: variables PlatformLang and PlatformLangCodes
Since TianoCore EDK2 commit d65f2cea36d1 ("ShellPkg/CommandLib: Locate
proper UnicodeCollation instance") in edk2 the UEFI Shell crashes if EFI
variable PlatformLang is not defined.

As this variable is anyway prescribed in the UEFI 2.7 spec let's define it
to L"en-US". Use the same value for PlatformLangCodes that defines the list
of all supported languages.

056b45bc50 efi_loader: move efi_init_obj_list() to a new efi_setup.c
The function, efi_init_obj_list(), can be shared in different pseudo efi
applications, like bootefi/bootmgr as well as my efishell. Moreover, it
will be utilized to extend efi initialization, for example, my "removable
disk support" patch and "capsule-on-disk support" patch in the future.

So with this patch, it will be moved to a new file, efi_setup.c, under
lib/efi_loader and exported, making no changes in functionality.
