Export KEY_ALG as a user build option ...

The `KEY_ALG` variable is used to select the algorithm for key
generation by `cert_create` tool for signing the certificates. This
variable was previously undocumented and did not have a global default
value. This patch corrects this and also adds changes to derive the
value of `TF_MBEDTLS_KEY_ALG` based on `KEY_ALG` if it not set by the
platform. The corresponding assignment of these variables are also now
removed from the `arm_common.mk` makefile.

Don't use zero_normalmem in bl2_platform_setup

Don't use zero_normalmem in bl2_platform_setup ...

zero_normalmem only can zero memory when caches are enabled
and the target memory is a normal memory, otherwise an abort is
generated. In the case of EL3_PAYLOAD_BASE bl2_platform_setup was
calling zero_normalmem with device memory and it generated an abort.

CORTEX_A57_ACTLR_EL1 macro refers to the CPUACTLR_EL1 register. Since
ACTLR_EL1 is a different register (not implemented in Cortex-A57) this
patch renames this macro for clarity.

plat/arm: Fix ARM_INSTANTIATE_LOCK syntax anomaly ...

The current definition of ARM_INSTANTIATE_LOCK macro includes a
semicolon, which means it's omitted where it's used. This is anomalous
for a C statement in global scope.

Fix this by removing semicolon from the definition; and where it's a
NOP, declare a file-scoped variable explicitly tagged as unused to avoid
compiler warning.

No functional changes.

FVP: Always assume shifted affinity with MT bit ...

At present, the MPIDR validation on FVP relies on MT bit set along
with shifted affinities. This currently is additionally dependent
on the FVP model being of variant C. This however should be based
on the presence of MT bit alone.

This patch makes the change to always assume that the affinities
are shifted in the FVP model when MT bit is present.

norflash: Add full status check ...

The nor_XXXXX functions may fail due to different reasons, and it
is convenient to do a full check to detect any failure. It is also
a good idea to have a specific function to do a full status check,
because new checks can be added to this function and they will be
incorporated automatically to any function calling it.

norflash: Clear status register before sending commands ...

The status register bits remain until explicitly cleared, which means
that a command can be incorrectly considered to have generated an error -
for example, after reset the status register contents may be unknown or
if a previous command had failed.

This patch clears the status register before beginning any command to
be sure that the status register only represents information about the
current operation.
