Alison Wang 020b3ce8ae armv8: Remove duplicate definition for IH_ARCH_ARM and IH_ARCH_ARM64
The duplicate definitions for IH_ARCH_ARM and IH_ARCH_ARM64 are removed.
The definitions in <image.h> are used.

According to this modification, the comparison between os arch and cpu
arch is done in C programming instead of ASM programming.
