In order for the symbol table in the ELF file to contain the size of
functions written in assembly, it is necessary to report it to the
assembler using the .size directive.

To fulfil the above requirements, this patch introduces an 'endfunc'
macro which contains the .endfunc and .size directives. It also adds
a .func directive to the 'func' assembler macro.

The .func/.endfunc have been used so the assembler can fail if
endfunc is omitted.

Fixes ARM-Software/tf-issues#295

This patch adds support to open/close secure sessions with Trusted
Apps and later send commands/events. Modify TLK_NUM_FID to indicate
the total number of FIDs available to the NS world.

This patch allows servicing of the non-secure world IRQs when the
CPU is in the secure world. Once the interrupt is handled, the
non-secure world issues the Resume FID to allow the secure payload
complete the preempted standard FID.

This patch adds functionality to translate virtual addresses from
secure or non-secure worlds. This functionality helps Trusted Apps
to share virtual addresses directly and allows the NS world to
pass virtual addresses to TLK directly.

This patch registers NS memory buffer with the secure payload using
two different functions IDs - REGISTER_LOGBUF, REGISTER_REQBUF.

a. The SP uses the log-buffer to store its activity logs, in a
pre-decided format. This helps in debugging secure payload's issues.
b. The SP uses the req-buffer to get the parameters required by
sessions with Trusted Applications.

TLK Dispatcher (tlkd) is based on the tspd and is the glue required
to run TLK as a Secure Payload with the Trusted Firmware.
