PATCH 1/1 initramfs should not depend on CONFIG_BLOCK

initramfs ended up depending on BLOCK:

INITRAMFS_SOURCE <-- BLK_DEV_INITRD <-- BLOCK

This inhibits use of customized-initramfs-over-ramfs without block layer (ramfs would still be enabled), useful in embedded applications.

Move BLK_DEV_INITRD out of 'drivers/block/Kconfig' and into 'init/Kconfig', make it unconditional.
