[PATCH v2 2/4] efi_loader: Kconfig: Add symbols for embedding the public key into the platform's dtb

[Sughosh Ganu]

Add config options EFI_PKEY_DTB_EMBED and EFI_PKEY_FILE which are to
be used for embedding the public key to be used for capsule
authentication into the platform's device tree.

The embedding of the public key would take place during the platform
build process.

Changes since V1:
* Provide a default name for public key file, eficapsule.esl as
  suggested by Heinrich.
* Remove the superfluous default n statement for EFI_PKEY_DTB_EMBED
