To avoid missing arm64 specific warnings that get introduced
in this driver, allow compile-testing on all 64-bit architectures.
The only actual arm64 specific code in this driver is an open-
coded 128 bit MMIO write. On non-arm64 the same can be done
using memcpy_toio. What I also noticed is that the mmio store
(either one) is not endian-safe, this will only work on little-
endian configurations, so I also add a Kconfig dependency on
that, regardless of the architecture.
Finally, a depenndecy on CONFIG_64BIT is needed because of the
writeq().

There are two problems in sec_free_hw_sgl():
First, when sgl_current->next is valid, @hw_sgl will be freed in the
first loop, but it free again after the loop.
Second, sgl_current and sgl_current->next_sgl is not match when
dma_pool_free() is invoked, the third parameter should be the dma
address of sgl_current, but sgl_current->next_sgl is the dma address
of next chain, so use sgl_current->next_sgl is wrong.
Fix this by deleting the last dma_pool_free() in sec_free_hw_sgl(),
modifying the condition for while loop, and matching the address for
dma_pool_free().
