security/tpm/crtm: Add a function to measure the bootblock on SoC level

On platforms where the bootblock is not included in CBFS anymore
(because it is part of another firmware section (IFWI or a different
CBFS), the CRTM measurement fails.

This patch adds a new function to provide a way at SoC level to measure
the bootblock. Following patches will add functionality to retrieve the
bootblock from the SoC related location and measure it from there.
In this way the really executed code will be measured.
