Move architecture timer setup to platform-specific code
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. Fixes ARM-software/tf-issues#24 Change-Id: I32c52cf882253e01f49056f47c58c23e6f422652
