core: add phys_mem allocation functions

Add nex_phys_mem and phys_mem allocation functions. These functions are
intended to replace the previous calls to tee_mm functions on with the
virt_mapper_pool or tee_mm_sec_ddr as arguments.

The pool of physical memory is divided into two parts, core and ta. All
physical TA memory allocations are done from the core pool if a ta pool
isn't added. This might be the case if core and ta physical memory
resides in the same physical memory range.

core: pager: fix compiler warning with Clang

Function rwp_unpaged_iv_free() is reduced to a call to panic() when
CFG_WITH_PAGER=y and CFG_CORE_PAGE_TAG_AND_IV=y. In this case, Clang 12
suggests a noreturn attribute:

$ make -s CFG_WITH_PAGER=y COMPILER=clang
core/mm/fobj.c:322:1: warning: function 'rwp_unpaged_iv_free' could be
declared with attribute 'noreturn' [-Wmissing-noreturn]
{

1 warning generated.

However the attribute cannot be applied since it would be inappropriate
when CFG_CORE_PAGE_TAG_AND_IV != y. Therefore, disable the warning for
the file core/mm/fobj.c when the problematic configuration is enabled.
