The terminology "mva" is specific for older ARM architecture which has

rename "mva" to common terminology, such as "va". This PR renames "mva"
to "va" in TLB operations for ARM64 and RISC-V. For ARM32, "mva" is
reserved because it is really defined in ARM32's documentations.

core: mm: Introduce next_level field of struct core_mmu_table_info

The address translation rule is architecture specific, e.g., ARM adopts
increasing style while the address is translated to finer-grained table,
while RISC-V adopts decreasing style. Therefore, we add a "next_level"
field into the struct core_mmu_table_info, which represents the next
finer-grained translation level. By doing this, we can decouple the
core address translation rule from architecture specific manner.

core: support physically relocatable OP-TEE binary

With CFG_CORE_PHYS_RELOCATABLE=y enable support in OP-TEE to relocate
itself to allow it to run from physical address that differs from the
link address.

This feature is currently only supported with CFG_CORE_SEL2_SPMC=y since
the TEE core has to know the range of available memory. With SPMC at EL2
this is accomplished via get_sec_mem_from_manifest(). An SPMC at S-EL2
may need to load OP-TEE at a different address depending on
configuration.

core: mm: fix error flushing unused pgt's

With commit b1df82f10633 ("core: use set_um_region() to update
translation tables") a "populated" value is used for each pgt
(translation table) to tell if it's up to date or if
core_mmu_populate_user_map() should initialize it.

When a pgt becomes unused it must be marked as unused. Prior to this
patch an error in the logic prevented pgt's to be marked as unused
properly. This can prevent core_mmu_populate_user_map() from
initializing a pgt. This can cause some new mappings to not be
established properly.

So fix this by giving the correct arguments for pgt_flush_range() in
rem_um_region() and core_is_buffer_inside() in pgt_entry_matches().

Many of the function in the pgt interface takes more than one pointer to
struct pgt_cache, struct vm_info or struct ts_ctx. All these pointers

instead. This saves a few function arguments and also makes it a bit
more clear how a function can be used.

pgt_clear_ctx_range(), pgt_flush_ctx_range() and pgt_flush_ctx() are
renamed to drop the "_ctx" part in their names since it's not relevant
any longer.
