    aarch64: add HXT Phecda core memory operation ifuncs
    
    Phecda is HXT semiconductor's CPU core, this patch adds memory operation
    ifuncs for it: sharing the same optimized implementation with Qualcomm's
    Falkor core.

    	* sysdeps/aarch64/multiarch/memcpy.c (libc_ifunc): reuse
    	__memcpy_falkor for phecda core.
    	* sysdeps/aarch64/multiarch/memmove.c (libc_ifunc): reuse
    	__memmove_falkor for phecda core.
    	* sysdeps/aarch64/multiarch/memset.c (libc_ifunc): reuse
    	__memset_falkor for phecda core.
    	* sysdeps/unix/sysv/linux/aarch64/cpu-features.c: add MIDR entry
    	for phecda core.
    	* sysdeps/unix/sysv/linux/aarch64/cpu-features.h (IS_PHECDA): add
    	macro to identify phecda core.
