memblock: add NO_BOOTMEM config symbol
With the NO_BOOTMEM symbol added architectures may now use the following
syntax to tell that they do not need bootmem:
select NO_BOOTMEM
This is much more convinient than adding a new kconfig symbol which was
otherwise required.
Adding this symbol does not conflict with the architctures that already
define their own symbol.
