ARM: 8430/1: use default ioremap alignment for SMP or LPAE
16MB alignment for ioremap mappings was added by commit a069c896d0d6 ("[ARM]
3705/1: add supersection support to ioremap()") in order to support supersection
mappings. But __arm_ioremap_pfn_caller uses section and supersection mappings
only in !SMP && !LPAE case. There is no need for such big alignment if either
SMP or LPAE is enabled.
After this change, ioremap will use default maximum alignment of 128 pages.
