Place assembler functions in separate sections This extends the --gc-sections behaviour to the many assembler support functions in the firmware images by placing each function into its own code section. This is achieved by creating a 'func' macro used to declare each function label.

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.
