arm/neon: dsputil: use correct size specifiers on vld1/vst1 Change the size specifiers to match the actual element sizes of the data. This makes no practical difference with strict alignment checking disabled (the default) other than somewhat documenting the code. With strict alignment checking on, it avoids trapping the unaligned loads. Signed-off-by: Mans Rullgard <mans@mansr.com>
