aarch64: Add Linux kernel hwcap string for FEAT_CSSC

The Linux kernel has done basic enablement and detection of FEAT_CSSC so
we can use the cpuinfo string that they've specified.

This patchlet does that.

Bootstrapped and tested on aarch64-none-linux-gnu.

gcc/ChangeLog:

	* config/aarch64/aarch64-option-extensions.def (cssc): Specify
	FEATURE_STRING field.
