ARMv7: introduce Cortex-A9

As Cortex-A9 needs to manually enable program flow prediction,
do not reset SCTLR[Z] at entry. Platform should enable it only
once MMU is enabled.

These macros are only defined for corresponding image,

Change sizeof to use type of struct not function

Change sizeof call so it references a static type instead of return of
a function in order to be MISRA compliant.

xlat: Introduce API to change memory attributes of a region

This patch introduces a new API in the translation tables library
(v2), that allows to change the memory attributes of a memory
region. It may be used to change its execution permissions and
data access permissions.

As a prerequisite, the memory must be already mapped. Moreover, it
must be mapped at the finest granularity (currently 4 KB).

xlat: Define translation regime in AArch32

Previously, in AArch32, `IMAGE_XLAT_DEFAULT_REGIME` wasn't defined. The
translation regime is only used in the AArch64 port of the translation
tables library v2, so this is not a problem for now, but future patches
will use it.

`IMAGE_EL` isn't used in AArch32, so it isn't needed to define it.
