x86/Kconfig: Turn off CONFIG_BLK_DEV_RAM

The vast majority of systems either use initramfs or mount a
root filesystem directly from the kernel.  Distros have
defaulted to initramfs for years.  Only highly specialized
systems would use an actual filesystem-image initrd at this
point, and such systems don't rely on defconfig anyway.  Drop
initrd support (and specifically RAM block device support) from
the defconfigs.
