soc/intel/apollolake: Measure bootblock from IFWI

On Apollo Lake the bootblock is stitched into the IBBL IFWI region at
build time. At execution time TXE loads this IBBL into a shared SRAM
(which is read-only in this phase) and maps it at 4 GiB - 32 KiB. Then
the CPU starts to operate from this shared SRAM as it were flash space.

In order to provide a reliable CRTM init, the real executed bootblock
code needs to be measured into TPM if VBOOT is selected. This patch adds
the needed code to do this.
