Add wrapper for AT instruction

In case of AT speculative workaround applied, page table walk
is disabled for lower ELs (EL1 and EL0) in EL3.
Hence added a wrapper function which temporarily enables page
table walk to execute AT instruction for lower ELs and then
disables page table walk.

Execute AT instructions directly for lower ELs (EL1 and EL0)
assuming page table walk is enabled always when AT speculative
workaround is not applied.

plat/arm: enable support for Plat owned SPs

For Arm platforms SPs are loaded by parsing tb_fw_config.dts and
adding them to SP structure sequentially, which in-turn is appended to
loadable image list.

With recently introduced dualroot CoT for SPs where they are owned
either by SiP or by Platform. SiP owned SPs index starts at SP_PKG1_ID
and Plat owned SPs index starts at SP_PKG5_ID. As the start index of SP
depends on the owner, there should be a mechanism to parse owner of a SP
and put it at the correct index in SP structure.

This patch adds support for parsing a new optional field "owner" and
based on it put SP details(UUID & Load-address) at the correct index in
SP structure.

Prevent colliding identifiers

There was a collision between the name of the typedef in the CASSERT and
something else, so we make the name of the typedef unique to the
invocation of DEFFINE_SVC_UUID2 by appending the name that's passed into
the macro. This eliminates the following MISRA violation:

bl1/bl1_main.c:233:[MISRA C-2012 Rule 5.6 (required)] Identifier
"invalid_svc_uuid" is already used to represent a typedef.

This also resolves MISRA rule 5.9.

These renamings are as follows:
* tzram -> secram. This matches the function call name as it has
sec_mem in it's name
* fw_config_base -> config_base. This file does not mess with
hw_conig, so there's little chance of confusion

plat/arm: Reduce size of BL31 binary

BL31 binary size is aligned to 4KB because of the
code in include\plat\arm\common\arm_reclaim_init.ld.S:
__INIT_CODE_UNALIGNED__ = .;
. = ALIGN(PAGE_SIZE);
__INIT_CODE_END__ = .;
with all the zero data after the last instruction of
BL31 code to the end of the page.
This causes increase in size of BL31 binary stored in FIP
and its loading time by BL2.
This patch reduces the size of BL31 image by moving
page alignment from __INIT_CODE_END__ to __STACKS_END__
which also increases the stack size for secondary CPUs.

tbbr/dualroot: rename SP package certificate file

Currently only single signing domain is supported for SP packages but
there is plan to support dual signing domains if CoT is dualroot.

SP_CONTENT_CERT_ID is the certificate file which is currently generated
and signed with trusted world key which in-turn is derived from Silicon
provider RoT key.
To allow dual signing domain for SP packages, other certificate file
will be derived from Platform owned RoT key.

This patch renames "SP_CONTENT_CERT_ID" to "SIP_SP_CONTENT_CERT_ID" and
does other related changes.
