Luis Araneda 44141474c0 ARM: zynq: Use memcpy_toio instead of memcpy on smp bring-up 
commit b7005d4ef4 upstream.

This fixes a kernel panic on memcpy when
FORTIFY_SOURCE is enabled.

The initial smp implementation on commit aa7eb2bb4e
("arm: zynq: Add smp support")
used memcpy, which worked fine until commit ee333554fe
("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE")
enabled overflow checks at runtime, producing a read
overflow panic.

The computed size of memcpy args are:
- p_size (dst): 4294967295 = (size_t) -1
- q_size (src): 1
- size (len): 8

Additionally, the memory is marked as __iomem, so one of
the memcpy_* functions should be used for read/write.

Fixes: aa7eb2bb4e ("arm: zynq: Add smp support")
