[kvm-unit-tests PATCH v4 1/2] x86 EFI: Bypass call to fdt_check_header()

[Pavan Kumar Paluri <papaluri@amd.com>]

Issuing a call to fdt_check_header() prevents running any of x86 UEFI
enabled tests. Bypass this call for x86 and also calls to
efi_load_image(), efi_grow_buffer(), efi_get_var() in order to enable
UEFI supported tests for KUT x86 arch.
