The variable is wrongly set to 0L, whereas it is an unsigned int, it should
then be 0U.

This patch adds support to handle following TLK SMCs:
{TLK_SET_BL_VERSION, TLK_LOCK_BL_INTERFACE, TLK_BL_RPMB_SERVICE}

These SMCs need to be supported in ATF in order to forward them to
TLK. Otherwise, these functionalities won't work.

Brief:
TLK_SET_BL_VERSION: This SMC is issued by the bootloader to supply its
version to TLK. TLK can use this to prevent rollback attacks.

TLK_LOCK_BL_INTERFACE: This SMC is issued by bootloader before handing off
execution to the OS. This allows preventing sensitive SMCs being used
by the OS.

TLK_BL_RPMB_SERVICE: bootloader issues this SMC to sign or verify RPMB
frames.

Tested by: Tests TLK can receive the new SMCs issued by bootloader

Hotplug poweron is not working for boot CPU as it's being
triggerred using PMC and not with Flow Controller. This is
happening because "cpu_powergate_mask" is only getting set
for non-boot CPU's as the boot CPU's first bootup follows
different code path. The patch is marking a CPU as ON within
"cpu_powergate_mask" when turning its power domain on
during power on. This will ensure only first bootup on all
CPU's is using PMC and subsequent hotplug poweron will be
using Flow Controller.

Streamid override registers are passed to memctrl to program bypass
streamid for all the registers. There is no reason to bypass SMMU
for any of the client so need to remove register list and do not
set streamid_override_cfg.

Some Tegra186 platforms don't boot due to SDMMC failure so keep SDMMC
bypass as of now. Will revisit once these issues are fixed.

When using the SPM Dispatcher, the SPMC sits as a BL32 component
(BL32_IMAGE_ID). The SPMC manifest is passed as the TOS fw config
component (TOS_FW_CONFIG_ID). It defines platform specific attributes
(memory range and physical CPU layout) as well as the attributes for
each secure partition (mostly load address). This manifest is passed
to the SPMC on boot up. An SP package contains the SP dtb in the SPCI
defined partition manifest format. As the SPMC manifest was enriched
it needs an increase of tos_fw-config max-size in fvp_fw_config dts.
