Revert "hw/sh4/r2d: Realize IDE controller before accessing it"

This reverts commit 3c5f86a22686ef475a8259c0d8ee714f61c770c9.

Changing the order here caused a regression with the "tuxrun"
kernels (from https://storage.tuxboot.com/20230331/) - ATA commands
fail with a "ata1: lost interrupt (Status 0x58)" message.
Apparently we need to wire the interrupt here first before
realizing the device, so revert the change to the original
behavior.
