In v5.7 the powerpc syscall entry/exit logic was rewritten in C, on PPC64_ELF_ABI_V1 this resulted in the symbols in the syscall table changing from their dot prefixed variant to the non-prefixed ones. Since ftrace prefixes a dot to the syscall names when matching them to build its syscall event list, this resulted in no syscall events being available. Remove the PPC64_ELF_ABI_V1 specific version of arch_syscall_match_sym_name to have the same behavior across all powerpc variants.
