[PATCH] m32r: bootloader support for OPSPUT platform

This patch supports "m32r-g00ff" bootloader for an OPSPUT platform.

Applying this patch, it is possible to do ATA-boot from an IDE drive or
HTTP-boot from network by m32r-g00ff.

    * arch/m32r/boot/compressed/m32r_sio.c: Fix hangup on OPSPUT at boot.

    * arch/m32r/kernel/io_opsput.c: IDE support for OPSPUT.
    * arch/m32r/kernel/setup_opsput.c: ditto.
    * include/asm-m32r/ide.h: ditto.
