scripts: use python's hex() in ta_bin_to_c.py

- Python has a built in function to turn a byte into its respective hex
value that can be used instead of string formatting the values
directly.
- Using the built in function instead of the previous string formatting
method fixed an issue where bytes were failing to be written when
we used an archaic yocto bsp from broadcom.
- The built in function also has the benefit of being easier to read and
understand.

core: armv7: fix ASLR error

With commit 528dabb28254 ("core: suppress text relocation on
stack_tmp_export") the stack pointer is calculated using a relative
address instead of based on an absolute address which is relocated with
ASLR enabled.

Prior to this on Armv7 we compensate for a relocation update for
stack_tmp_export_rel in reset_secondary() just after the stack pointer
was initialized. So now when the relocation update of stack_tmp_export_rel
is gone remove the compensating code too.

core: sp: handle memory regions w/o base address

The FF-A spec states that in the SP manifest a base address is not
mandatory for memory regions. If the field is not present, the specified
memory region must be allocated by the SPMC and mapped to the SP's
context.

A copy of the SP manifest fdt is used for passing the memory region
virtual addresses to the SP. Additional space is allocated when copying
the fdt so the originally not present base address fields can be added
later.

Currently the SP manifest processing only handles the device regions,

Note: if the region's base address is a PA, according to the FF-A spec
it has to be identity mapped to the same VA. This requirement will be
removed in the spec's next version, so the current implementation should
be acceptable.

plat-sam: add timer clock driver

Add support for the TCB block that are present on the samad2. This
series add support for the TCB as a time source and register it using
REGISTER_TIME_SOURCE(). Moreover, on Linux, the tick is done using the
TCB since the sama5d2 does not have the ARM architected timers. Since
the time source used for the tick clocksource is probed early in the
boot process, the SCMI clock support which uses a platform driver is
not yet probed and thus the TCB can't be probe properly. To workaround
that problem, this driver enables the TCB clocks and the Linux
device-tree is modified to use "fixed-clock" clock instead of the TCB
SCMI ones.

a valid pointer. Initializing prng_state in some configurations
can get very large. For instance, xtest for X25519 key generation
causes the TA to panic due to stack overrun
