Revert "Move architecture timer setup to platform-specific code"
This reverts commit 1c297bf015226c182b66498d5a64b8b51c7624f5
because it introduced a bug: the CNTFRQ_EL0 register was no
longer programmed by all CPUs. bl31_platform_setup() function
is invoked only in the cold boot path and consequently only
on the primary cpu.
A subsequent commit will correctly implement the necessary changes
to the counter frequency setup code.
Fixes ARM-software/tf-issues#125
