Tamas Ban c44e50b725 feat(plat/arm/fvp): enable RSS backend based measured boot
Enable the RSS backend based measured boot feature.
In the absence of RSS the mocked version of PSA APIs
are used. They always return with success and hard-code data.

Manish V Badarkhe 426a111965 refactor(measured boot): rename a macro INVALID_ID to EVLOG_INVALID_ID
Renamed a macro 'INVALID_ID' to 'EVLOG_INVALID_ID' to avoid its clash
with other macro names and to show it is explicitly used for Event
Log driver.

Manish V Badarkhe 8a89e1898b refactor(measured boot): make measurement strings compliant with SBSG
Made measurement strings compliant to Server Base Security Guide
(SBSG, Arm DEN 0086) hence updated measurement strings for BL32, BL31,
and SCP_BL2 images. As the GPT image is not get measured by BL2 so
removed its measurement string.
Also, namespaced measurement string defines that were looking quite
generic.

Manish V Badarkhe 0500f4479e feat(plat/fvp): pass Event Log addr and size from BL1 to BL2
Introduced functions to set and get Event log information
(tpm_event_log address and its size).

In FVP platform case, measured boot with Event Log backend flow
work as below
1. event_log_init function called by BL1 to initialize Event Log
   module
2. arm_set_tb_fw_info function called by BL1 to set the
   'tpm_event_log_addr' and 'tpm_event_log_size' properties
   in tb_fw_config
3. arm_get_tb_fw_info function called by BL2 to get tpm Event Log
   parameters set by BL1. These parameters used by the BL2 to
   extend the tpm Event Log records, and use these parameters
   to initialize Event Log using event_log_init function
4. arm_set_nt_fw_info and arm_set_tos_fw_info function called by
   BL2 to set 'tpm_event_log' address and its size properties in
   nt_fw_config and tos_fw_config respectively

Alongside, this patch created a separate instances of plat_mboot_init
and plat_mboot_finish APIs for BL1 and BL2.

This patch is tested using the existing measured boot test configuration
in jenkins CI.

Manish V Badarkhe 48ba0345f7 feat(measured_boot): image hash measurement and recording in BL1
It looks safer and cleaner approach to record the measurement taken by
BL1 straightaway in TCG Event Log instead of deferring these recordings
to BL2.
Hence pull in the full-fledged measured boot driver into BL1 that
replaces the former ad-hoc platform interfaces i.e.
bl1_plat_set_bl2_hash, bl2_plat_get_hash.

As a result of this change the BL1 of Arm FVP platform now do the
measurements and recordings of below images:
1. FW_CONFIG
2. TB_FW_CONFIG
3. BL2
