Mostafa Saleh 442d366cc1 arm64/mm: Simplify SWIOTLB setup in arch_mm_preinit() ...

At the moment, arch_mm_preinit() checks if the system has limited
addressing or is running under CCA to enable SWIOTLB, only after to
be forced to true anyway if it was false due to
CONFIG_DMA_BOUNCE_UNALIGNED_KMALLOC being unconditionally true for
arm64.

Simplify this logic, by making it clear that SWIOTLB is always used
but its size depends on the address layout of the system.
