hw/timer/sh_timer: Remove use of hw_error 

The hw_error function calls abort and is not meant to be used by
devices. Use qemu_log_mask instead to log and ignore invalid accesses.
Also fix format strings to allow dropping type casts of hwaddr and use
__func__ instead of hard coding function name in the message which
were wrong in two cases.
