Restructure framework's directory hierarchy

This is a first, rough attempt at cleaning the framework's directory
hierarchy.

Basically, almost everything is moved to individual directories
under lib/. What's left under framework/ are the core features of
the framework, i.e. things that test cases won't ever need.

This patch also introduces some cleanups.

The following functions are removed:

 - tftf_platform_get_time()
   We'll need such a function in the future to measure tests execution
   time but there's no reason for it to be platform-specific, we can
   use the Generic Timer instead when we get to it.
   Tracked by GENFW-506.

 - tftf_platform_reset()
   We'll need a function to reset the platform in the future but at
   the moment it is not used.
   Tracked by GENFW-500.

 - tftf_platform_core_whoami()
   Not needed. A CPU can just call read_mpidr_el1() to get its MPID,
   then platform_get_core_pos() to get the corresponding linear ID.
   See GENFW-483.

 - tftf_is_core_enabled()
   Superseded by plat_get_aff_state().

 - tftf_core_participates_in_testcase()
   Superseded by the platform API to query the platform topology.

Move the following defintions out of framework/helpers.c:

 - Move mp_printf() in lib/utils/mp_printf.c
 - Move MMU functions into plat_common.c as default implementations
   of these platform functions.

What's left in helpers.c then are helper functions to write test
results into NVM so rename the file into nvm_results_helpers.c.

Remove bl_common.h as it contains only Trusted Firmware specific
definitions.

Rename tests_api.h into tftf_lib.h. Also move some of its
declarations into new header files: irq.h, systimer.h, sgi.h.

Remove tftf_common.h and move its declarations to tftf_lib.h.

Rename rt_services/ into runtime_services/.

The test cases' directory hierarchy needs to be restructured as well,
this will come in a subsequent patch.
