feat(arm): add COT_DESC_IN_DTB option for CCA CoT

Add support for BL2 to get the CCA chain of trust description
through the Firmware Configuration Framework (FCONF). This makes
it possible to export the part of the CCA chain of trust enforced
by BL2 in BL2's configuration file (TB_FW_CONFIG DTB file). BL2
will parse it when setting up the platform.

This feature can be enabled through the COT_DESC_IN_DTB=1 option.
The default behaviour (COT_DESC_IN_DTB=0) remains to hard-code
the CCA CoT into BL2 image.
