Subject: [PATCH v5 1/4] mm: Remove now defunct NO_BOOTMEM from depends list
 for deferred init

The CONFIG_NO_BOOTMEM config option was recently removed by the patch "mm:
remove CONFIG_NO_BOOTMEM" (https://patchwork.kernel.org/patch/10600647/).
However it looks like it missed a few spots. The biggest one being the
dependency for deferred init. This patch goes through and removes the
remaining spots that appear to have been missed in the patch so that I am
able to build again with deferred memory initialization.
