This patch further optimizes the EL3 register state stored in
cpu_context. The 2 registers which are removed from cpu_context are:
* cntfrq_el0 is the system timer register which is writable
only in EL3 and it can be programmed during cold/warm boot. Hence
it need not be saved to cpu_context.
* cptr_el3 controls access to Trace, Floating-point, and Advanced
SIMD functionality and it is programmed every time during cold
and warm boot. The current BL3-1 implementation does not need to
modify the access controls during normal execution and hence
they are expected to remain static.
Fixes ARM-software/tf-issues#197
