m32r: Rename STI/CLI macros
The names of STI and CLI macros were derived from i386 arch historically, but their name are incomprehensible. So, for easy to understand, rename these macros to ENABLE_INTERRUPTS and DISABLE_INTERRUPTS, respectively. Signed-off-by: Hirokazu Takata <takata@linux-m32r.org>
