[PATCH v5 3/3] efi_loader: add FIT_SIGNATURE option to use hash_calculate()

[Masahisa Kojima]

Build error occurs when CONFIG_EFI_SECURE_BOOT/
CONFIG_EFI_CAPSULE_AUTHENTICATE/CONFIG_EFI_TCG2_PROTOCOL
is enabled, because hash-checksum.c is not compiled.

With the following commit,
commit 0bcb28dfb946 ("lib: Rename rsa-checksum.c to hash-checksum.c")
CONFIG_FIT_SIGNATURE option is required to use hash_calculate() function.

This commit selects FIT_SIGNATURE option in Kconfig.

- Missing option for EFI_TCG2_PROTOROL already added in different commit.

Changes in v4:
- newly added in this patch series, due to rebasing
  the base code.
