Jan Kiszka 2959c95d51 efi/capsule: Add support for Quark security header
The firmware for Quark X102x prepends a security header to the capsule
which is needed to support the mandatory secure boot on this processor.
The header can be detected by checking for the "_CSH" signature and -
to avoid any GUID conflict - validating its size field to contain the
expected value. Then we need to look for the EFI header right after the
security header and pass the real header to __efi_capsule_setup_info.

To be minimal invasive and maximal safe, the quirk version of
efi_capsule_setup_info() is only effective on Quark processors.
