FVP: Add dummy configs for BL31, BL32 and BL33

This patch adds soc_fw_config, tos_fw_config and nt_fw_config to the FVP.
The config files are placeholders and do not have any useful bindings
defined. The tos_fw_config is packaged in FIP and loaded by BL2 only
if SPD=tspd. The load address of these configs are specified in tb_fw_config
via new bindings defined for these configs. Currently, in FVP, the
soc_fw_config and tos_fw_config is loaded in the page between BL2_BASE
and ARM_SHARED_RAM. This memory was typically used for BL32 when
ARM_TSP_RAM_LOCATION=tsram but since we cannot fit BL32 in that
space anymore, it should be safe to use this memory for these configs.
There is also a runtime check in arm_bl2_dyn_cfg_init() which ensures
that this overlap doesn't happen.

The previous arm_dyn_get_hwconfig_info() is modified to accept configs
other than hw_config and hence renamed to arm_dyn_get_config_load_info().
The patch also corrects the definition of ARM_TB_FW_CONFIG_LIMIT to be
BL2_BASE.

FVP: Enable capability to disable auth via dynamic config

This patch adds capability to FVP to disable authentication dynamically
via the `disable_auth` property in TB_FW_CONFIG. Both BL1 and BL2 parses
the TB_FW_CONFIG for the `disable_auth` property and invokes the
`load_dyn_disable_auth()` API to disable authentication if the
property is set to 1. The DYN_DISABLE_AUTH is enabled by default for
FVP as it is a development platform. Note that the TB_FW_CONFIG has to
be authenticated by BL1 irrespective of these settings.

The arm_bl2_dyn_cfg_init() is now earlier in bl2_plat_preload_setup()
rather than in bl2_platform_setup() as we need to get the value of
`disable_auth` property prior to authentication of any image by BL2.

In 'console_set_scope' and when registering a console, field 'flags' of

used, the functions perform 64-bit reads to access its value. This patch
changes all 64-bit reads to 32-bit reads.

to get this info from pmufw instead of directly accessing
the registers. Accessing this info from pmufw using

After sending PM_SYSTEM_SHUTDOWN request to PMU, PMU will

of OCM, which can cause read/write hang from/to OCM.
There is no need to wait for notification from PMU in case
