virt: add nexus memory area
This patch is the first in series of patches that split OP-TEE RW memory
into two regions: nexus memory and TEE memory. Nexus memory will
be always mapped and it will be used to store all data that is
vital for OP-TEE core and is not bound to virtual guests.
TEE memory is a memory that holds data specific for certain guest.
There will be TEE memory bank for every guest and it will be mapped
into OP-TEE address space only during call from that guest.
This patch adds nexus memory and moves stacks into it. Also
it provides __nex_bss and __nex_data macros, so one can easily set right
section for a variable.
