If no IRQ request is found in the IRQ check of ei_handler,
we can exit directly by jumping "restore_all", instead of via
"ret_from_intr".
This modification is also likely effective for IPI operations,
because scheduler call never happen at the exit of IPIs.

Simplify and clean up messy ei_handler code in arch/m32r/kernel/entry.S.
- Remove ifdef's for CONFIG_CHIP_* configulations.
- Rearrange the M32700 workaround code.
- Remove the messy platform-dependent interrupt check routines and
consolidate them to common INT0/INT1/INT2 check routines for all
platforms with cascaded interrupt controllers.

On some m32r platforms, cascaded ICUs are used.
This patch is required to simplify ei_handler and consolidate platform-
dependent ICU check routines.
