gpt_runtime_init() now takes the bitlock array's address and size as
argument. Rather than reserving space at the end of the L0 GPT for
storing bitlocks, allocate a static array and pass its address to
gpt_runtime_init(). This frees up a little bit of space formerly
reserved for alignment of the GPT.

If TRANSFER_LIST is enabled, hand off TPM event log via TL instead
of DT; otherwise fallback to legacy way if TRANSFER_LIST is off or
errors observed.
Moreover, for updating the TL from secure to non-secure
memory before existing EL3, replace memcpy with function
transfer_list_relocate() for more accuracy.

The commit with Change-Id:Ie417e054a7a4c192024a2679419e99efeded1705
updated the register convention r1/x1 values but missing necessary
changes in BL31.
As a result, a system panic observed during setup for BL32 when
TRANSFER_LIST is enabled due to unexpected arguments.
This patch is to fix this issue for qemu.

The amount of memory supported by the SBSA platform is dynamic
and dependent on user input. Since the configuration of the GPT
needs to reflect the system memory, QEMU_PAS_NS0 needs to be set
based on the information found in the device tree.

There is no relation between the name of function sip_svc_init() and
what it does. As such rename it to something more appropriate and move
it to a header that make sense.
No change in functionality.

Add a new parameter to make the size of the L0GPT configurable based on
the amount of memory available on a platform. That way platform with a
wider physical address range can be supported.
No change in functionality.

Some platforms such as QEMU-SBSA access the device tree located at the
bottom of the non-secure RAM from BL31. When GPT checks are enabled at
BL2, that access generates a GPT check fault because the device tree
area is configure as non-secure RAM and the access is made from secure
EL3.
We could change the device tree memory area configuration in a way that
it is accessible from BL31, but that would require another configuration
of the GPT before going to BL33.
Since BL2 and BL31 are both running at EL3, a better solution is simply
move the GPT configuration and enabling to BL31, after the device tree
has been probed.
No change in functionality.

From QEMU change:
> In previous versions of the Arm architecture, the frequency of the
> generic timers as reported in CNTFRQ_EL0 could be any IMPDEF value,
> and for QEMU we picked 62.5MHz, giving a timer tick period of 16ns.
> In Armv8.6, the architecture standardized this frequency to 1GHz.
This change stops TF-A from hardcoding 62.5MHz frequency. Instead value
stored in CNTFRQ_EL0 would be used. As a result we get 62.5MHz on older
cores and 1GHz on newer ones.

Flush the FIFO before switching to runtime. This is so that there are
no lingering chars in the FIFO when we move to the runtime console.
TF-A plans to refactor the console_Switch_state(CONSOLE_FLAG_RUNTIME)
and console_flush() calls and make them the last calls in bl31_main()
(before BL31 exits). Until then they are being left as the last calls
in bl31_plat_runtime_setup() for testing before refactoring.
This patch affects the QEMU platform only.

Fallback to default handoff args when transfer list is disabled or
fails to archieve args from transfer entries.
Refactor handoff from BL2 to BL33.

This commit change the plat/qemu directory structure into:
`-- plat
`-- qemu
|-- common (files shared with all qemu subplatforms)
|-- qemu (original qemu platform)
|-- qemu_sbsa (new sqemu_sbsa platform)
|-- subplat1
`-- subplat2
This opens the possibility of adding new qemu sub-platforms which reuse
existing common platform code. The first platform which will leverage new
structure will be SBSA platform.
