core: add flash_subpart_info()
Currently, the CAPP lid has the TOC (4K) and one supartition (36K). For
secure boot we can either build one container for the TOC and another one for
the subpartition, or build one container for the whole CAPP partition.
We decided implement the second option.
The first option would require changes to the CAPP TOC layout in order to
correlate the TOC with the subpartitions. Besides that, the first option
also increases the boot time since we would need to verify and measure
the CAPP TOC.
This patch adds the flash_subpart_info function so the correct CAPP
subpartition can be selected also outside of the flash API.
