phys_to_virt() function without length parameter doesn`t
always have ability to find the correct mapping for
requested physical address. This is because physical
address can be mapped in the same time in different virtual
regions with different length. So the first found region
which contains the requested physical address possibly
doesn`t have enough mapped data. This is fixed by adding
the length parameter to phys_to_virt() function. Length
parameter can be set to 1 if caller knows that requested
(pa + len) doesn`t cross mapping granule boundary.
core_mmu_get_va() and io_pa_or_va() functions now are
take length parameter too as they based on phys_to_virt()
in case of MMU enabled.

This change applies to arm32 assembler sources.
Instead of using UNWIND(.fnstart) after FUNC or LOCAL_FUNC and
UNWIND(.fnend) before END_FUNC, let's fold these statements into the
FUNC macros.
The .fnstart/.fnend directives mark the start and end of a function
with an unwind table entry (.ARM.exidx) and therefore a function
without them has no entry and cannot be unwound. This means that a
stack dump (on abort or panic) would stop when reaching such a
function.
As a result of this patch, a small number of functions now have an
entry in the unwind table when they had none before (the functions
which were using FUNC or LOCAL_FUNC but had no .fnstart/.fnend). It was
almost always a bug and this pacth only increases the size of the
.ARM.exidx section by a few bytes (tested on QEMU).

All the users of the UNWIND() macro include <asm.S> already, which is
therefore a good place to define this macro. Let's move it from
<kernel/unwind.h> to <asm.S>, remove a couple of duplicates in
assembler files, and drop the useless includes.

struct thread_handlers is used to pass the entry functions
for different power management events. In practice only .cpu_on is used
and with the default function at that. In the ARMv7 case where the
secure monitor replaces TF-A not even that function entry is used.
Remove struct thread_handlers and boot_get_handlers(). When configured
with TF-A initialize thread_*_handler_ptr with __weak default functions.
The __weak default PM functions
- thread_cpu_off_handler()
- thread_cpu_suspend_handler()
- thread_cpu_resume_handler()
- thread_system_off_handler()
- thread_system_reset_handler()
can be overridden by platforms when needed.

All platforms but one (bcm-ns3) set CFG_WITH_STACK_CANARIES ?= y in
their configuration files. Move this flag to the global mk/config.mk
instead. Not sure it matters much, but in order to avoid any functional
change, CFG_WITH_STACK_CANARIES ?= n is added to plat-bcm/conf.mk.

As per Arm SMCCC v1.1 specification [1], PSCI PSCI_FEATURES function ID
should report Arm Architecture Call SMCCC_VERSION as supported when
the secure firmware supports both PSCI PSCI_FEATURES function ID and
Arm SMCCC_VERSION function ID.

Removes registration of platform specific secure interrupt handler in
thread_nintr_handler_ptr. Instead a __weak overridable
itr_core_handler() is provided. Platforms which expects to receive
secure interrupts must override the default function. The default
function calls panic() if called.
With this also nintr is removed from struct thread_handlers and
consequently all platforms are updated to stop using that field.

Removes registration of platform specific fast SMC entry function in
thread_fast_smc_handler_ptr. Instead a __weak overridable
tee_entry_fast() is provided. Platforms that need a special
tee_entry_fast() (currently on plat-zynq7k) provides their own
tee_entry_fast() instead which at the end should call __tee_entry_fast()
which does the generic fast call handling.
With this also fast_smc is removed from struct thread_handlers and
consequently all platforms are updated to stop using that field.
