core: arch: arm correct mme.va initialization
core: arch: arm correct mme.va initialization

mme.va should be initialized using map[n].va, but not map[n].pa.

Now map[n].pa can make all work, because we use 1 to 1 mapping with
virtual address same to physical address.

Later, we need to implement that virtual address not equal to physical
address to avoid address conflicting with user ta address and optee os
kernel address(<= 64M).
