[AArch64] Add support for Cortex-A35

This patch adds support to the AArch64 back-end for the Cortex-A35
processor, as recently announced by ARM. The ARM Cortex-A35 provides
full support for the ARMv8-A architecture, including the CRC extension,
with optional Advanced-SIMD and Floating-Point support. We therefore set
feature flags for this CPU to AARCH64_ARCH_V8 and AARCH64_FEATURE_CRC, in
the same fashion as Cortex-A53 and Cortex-A57.

Tested in a cross environment for AArch64 with no issues.
