memblock: emphasize that memblock_alloc_range() returns a physical address

Rename memblock_alloc_range() to memblock_phys_alloc_range() to
emphasize that it returns a physical address.

While on it, remove the 'enum memblock_flags' parameter from this
function as its only user anyway sets it to MEMBLOCK_NONE, which is the
default for the most of memblock allocations.
