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.
