core: mm: change vm_pa2va() to return a virtual address

Change vm_pa2va() to return target virtual address or NULL if the
physical address cannot be resolved which can happen when pager is
enabled and the target physical page belongs to the pager page pool.
This change makes vm_pa2va() helper function simpler and its only caller
doesn't differentiate error return codes.

core: fobj_rw_paged_alloc() store tags and IVs in paged area

fobj_rw_paged_alloc() is updated to store tags and IVs in a designated
paged area instead of storing them in the heap. This avoids large heap
allocations which also would suffer from a fragmented heap.

The previous ops_rw_paged and struct fobj_rwp are now replaced by
ops_rwp_unpaged_iv and struct fobj_rwp_unpaged_iv respectively. These
are now only used to support the area where other tags and IVs are
stored.

A new ops_rwp_paged_iv and struct fobj_rwp_paged_iv are added for
using the designated paged area.

A fobj based on the ops_rwp_unpaged_iv ops is allocated and registered
with the pager via a callback registered with driver_init_late().

This effectively enables paging of IV and tags for pages mapping a TA.

core: pager: support paging of tag and IV

Adds support for paging of the tag and IV protecting some read-write
fobjs. The tag and IV needed to decrypt/encrypt a page are accessed by
the pager. Since the pager can't handle page fault caused by itself
special measures are taken to make sure that the needed tag and IV are
accessible when needed.

tee_pager_get_page() and tee_pager_load_page() are replaced by
pager_get_page() which does what the previous functions used plus the
additional logic to handle paging of tag and IV.

A new function tee_pager_init_iv_area() is added. It enables
registration of a read/write paged fobj spanning the area used for
storing all tags and IVs. This fobj must store its tags and IVs in
unpaged memory, for instance the heap.
