At present, bl1_arch_setup() and bl31_arch_setup() program the counter
frequency using a value from the memory mapped generic timer. The
generic timer however is not necessarily present on all ARM systems
(although it is architected to be present on all server systems).
This patch moves the timer setup to platform-specific code and updates
the relevant documentation. Also, CNTR.FCREQ is set as the specification
requires the bit corresponding to the counter's frequency to be set when
enabling. Since we intend to use the base frequency, set bit 8.

Consolidate firmware-design.md and porting-guide.pm so
that recently added sections fit better with
pre-existing sections. Make the documentation more
consistent in use of terminology.

1. Add design information on EL3 runtime services and
Secure-EL1 Payload Dispatchers (SPD) to
firmware-design.md.
2. Create new EL3 runtime service writer's guide
(rt-svc-writers-guide.md) to ease creation of new
runtime services.

Move the firmware design documentation out of user-guide.md
and into a new file - firmware-design.md. Reformat the
section headers.
