In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously. Convert all of these to the correct SPDX-License-Identifier
tag.

addrmap_phys_to_virt() converts a physical address (phys_addr_t) to a
virtual address, so it should return a pointer instead of an unsigned long.
Its counterpart, addrmap_virt_to_phys(), takes a pointer, so now they're
orthogonal.
The only caller of addrmap_phys_to_virt() converts the return value to
a pointer anyway.

Add a library that helps in translating between virtual and physical
addresses. This library can be useful as a simple means to implement
map_physmem() and virt_to_phys() for platforms that need functionality
beyond the simple 1:1 mapping.
