Add support to indicate size and end of assembly functions
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
