cinap_lenrek 21a599743e pc, pc64: merge adjacent e820 map entries of same type 
some machines give us over 300 e820 ram entries that are
all adjacent to each other causing us to run out of Map
end Emap entries.

this change adds e820clean() function, which sorts the
current e820 map and discards unusable entries and merges
adjacent entries. e820clean() is called after we parsed
the *e820= boot parameter or when we run out of entries.

an example of such a broken e820 map (thanks mischief):
