ARMv7 and Cortex-A32(ARMv8/aarch32) uses "arm-linux-gnueabi" toolchain which
has both soft-float and hard-float variants and so there could be scenarios
where soft-float toolchain is used.Even though TF-A documentation recommends
to use hard-float toolchain for aarch32 but there are external projects where
we cannot mandate the selection of toolchain and for those projects at least
the build should not fail.
Current TF-A source fails to build with soft-float toolchain because assembler
does not recognizes "vmsr" instruction which is required to enable floating
point unit.
To avoid this piece of code being compiled with soft-float toolchain add
predefined macro guard " __SOFTFP__" exposed by soft-float toolchain.

Cortex A5 doesnt support VFP, Large Page addressing and generic timer
which are addressed in this patch. The device tree for Cortex a5
is also included.

In a system with ARMv8.5-PMU implemented:
- If EL3 is using AArch32, setting MDCR_EL3.SCCD to 1 disables counting
in Secure state in PMCCNTR.
- If EL3 is using AArch64, setting SDCR.SCCD to 1 disables counting in
Secure state in PMCCNTR_EL0.
So far this effect has been achieved by setting PMCR_EL0.DP (in AArch64)
or PMCR.DP (in AArch32) to 1 instead, but this isn't considered secure
as any EL can change that value.

The architecture dependant header files in include/lib/${ARCH} and
include/common/${ARCH} have been moved to /include/arch/${ARCH}.
