Rename e820_mapped to e820_any_mapped

From: Arjan van de Ven <arjan@linux.intel.com>

Rename e820_mapped to e820_any_mapped since it tests if any part
of the range is mapped according to the type. Later steps will introduce
e820_all_mapped which will check if the entire range is mapped with the type.
Both have their merit.
