Remove dead code, unused definitions and stream-line the code.

The topology code was apparently copied from the ARM FVP model, which
is very versatile and allows for a sophisticated, configurable topology
setup.
Allwinner SoC on the other hand are at best multi-cluster - the A64 in
fact has only one cluster.
Simplify the sunxi specific topology code to support two affinity
levels at most - this drastically reduces the code size and makes
it much more readable.

The architected timer is hardwired to be driven by the 24 MHz clock.
Remove all code that tries to determine this dynamically.
Also fix the actual number, which is not 24 * 2^20, but 24 * 10^6 Hz.

Add some constants to the console code to make it more readable.

A lot of code is not needed:
- no need for empty function which have a default implementation
- no need for A57 code and Juno workarounds
- no need for specific core enumeration in a single cluster SoC

Allwinner removed "-pedantic" from the list of CFLAGS to get away
with some conditional debug macros using a GNU extension.
Fix those macros to use a standard compliant syntax and re-enable
-pedantic.

The Pine64 Wiki[1] links to a BSP tarball, among other things
containing a dump of an ARM Trusted Firmware source tree with
Allwinner changes on top.
Since the tarball does not contain any version history information
about the changes, this commit is just the diff between the ATF 1.0
release and the files from the Allwinner provided tarball.
The executable flag from many source has been removed.
