Jeremy Compostella 3dcd0d98e4 libpayload: Add VBOOT_X86_RSA_ACCELERATION config
Add `VBOOT_X86_RSA_ACCELERATION' Kconfig option to enable SSE2
instruction set implementation of modulus exponentiation which is part
of the RSA signature verification process. This option is enabled on
CHROMEOS.

Jakub Czapiga 1fa3da4d9b libpayload: Enable vboot integration
This patch introduces building and linking of 3rdparty/vboot with
libpayload. VBoot can be enabled by setting CONFIG_LP_VBOOT_LIB.
Moreover it can be configured to use either TPM or TPM 2.0 mode,
and whether to use SHA256 processor extension instructions on x86.
