Remove variables from .data section
Update code base to remove variables from the .data section, mainly by using const static data where possible and adding the const specifier as required. Most changes are to the IO subsystem, including the framework APIs. The FVP power management code is also affected. Delay initialization of the global static variable, next_image_type in bl31_main.c, until it is realy needed. Doing this moves the variable from the .data to the .bss section. Also review the IO interface for inconsistencies, using uintptr_t where possible instead of void *. Remove the io_handle and io_dev_handle typedefs, which were unnecessary, replacing instances with uintptr_t. Fixes ARM-software/tf-issues#107. Change-Id: I085a62197c82410b566e4698e5590063563ed304
