ENGR00216013-2 mx6: not call memblock_free after reserve memory.
Remove call memblock_free after reserve memory with memblock_allocate().
The function of memblock_free is to remove the memory block from reserve list
of memblock, it will totally lost the info about how much phy memory
we have.
Skipping call this can make the reserved memory be accountable in
memblock With no side-effect.
After doing this, we can know how much our phy memory is, then can add check
in our driver like(vpu) to check the phy memory valid or not before vpu start
use the address.
