The tf_printf library uses 64 bit division to print numbers
in appropriate formats but AArch32 mode cannot do 64 bit division
natively. Hence this patch adds additional number printing routines
to handle AArch32 mode in tf_printf library. The decimal format
printing capability is limited to 32 bit integers whereas 64 bits
are supported in hexadecimal format. The library assumes that
secure world is running in Little-Endian mode to do bit
manipulations on 64 bit. Suitable assertions are present to
enforce this assumption.

This patch adds support to differentiate between `long` and `long long`
format specifiers in tf_printf(). In AArch64, they are the same which is
a 64-bit word. But, in AArch32 they are different and tf_printf() needs
to handle these format specifiers separately. This patch also fixes the
type of variables used to generic C types.

This patch adds support for the `%p` format specifier in tf_printf()
following the example of the printf implementation of the stdlib used
in the trusted firmware.

All coding style violations have been fixed in a previous patch and
since then, each individual patch has been checked in this regard.
However, the latest version of the checkpatch.pl script from the Linux
kernel is more advanced and it is able to flag new errors in the
Trusted Firmware codebase. This patch fixes them.

This patch implements a "tf_printf" which supports only the commonly
used format specifiers in Trusted Firmware, which uses a lot less
stack space than the stdlib printf function.
