[PATCH] 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.

+	help
+	  The initial RAM filesystem is a ramfs which is loaded by the
+	  boot loader (loadlin or lilo) and that is mounted as root
+	  before the normal boot procedure. It is typically used to
+	  load modules needed to mount the "real" root file system,
+	  etc. See <file:Documentation/initrd.txt> for details.
+
+	  If RAM disk support (BLK_DEV_RAM) is also included, this
+	  also enables initial RAM disk (initrd) support and adds
+	  15 Kbytes (more on some other architectures) to the kernel size.
