[PATCH][BINUTILS] aarch64: Add ite feature system registers

[Srinath Parvathaneni]

Hi,

This patch adds ite feature (FEAT_ITE) system registers,
trcitecr_el1, trcitecr_el12, trcitecr_el2 and trciteedcr.

Regression tested for aarch64-none-elf target and found
no regressions.

Ok for binutils-master?

Regards,
Srinath.
