[PATCH] USB: Make ISD-200 USB/ATA Bridge depend on BLK_DEV_IDE

This usb driver needs ide_fix_driveid from drivers/ide/ide-ops.c, which
needs BLK_DEV_IDE ("Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy
support") to get built.

Without this patch, you can configure an un-linkable kernel by doing make
allnoconfig, make menuconfig, and setting CONFIG_PCI, CONFIG_USB,
CONFIG_USB_STORAGE, and CONFIG_USB_STORAGE_ISD200 only.
