m68k: reword ARCH_FORCE_MAX_ORDER prompt and help text 

The prompt and help text of ARCH_FORCE_MAX_ORDER are not even close to
describe this configuration option.

Update both to actually describe what this option does.

	  The kernel memory allocator divides physically contiguous memory

	  blocks into "zones", where each zone is a power of two number of

	  pages.  This option selects the largest power of two that the kernel

	  keeps in the memory allocator.  If you need to allocate very large

	  blocks of physically contiguous memory, then you may need to

	  increase this value.

	  The kernel page allocator limits the size of maximal physically

	  contiguous allocations. The limit is called MAX_ORDER and it

	  defines the maximal power of two of number of pages that can be

	  allocated as a single contiguous block. This option allows

	  overriding the default setting when ability to allocate very

	  large blocks of physically contiguous memory is required.



	  For systems that have holes in their physical address space this

	  value also defines the minimal size of the hole that allows

	  freeing unused memory map.



	  Don't change if unsure.
