6c9a60ada4 avcodec/loongarch: Add wrapper for __lsx_vldx 
__lsx_vldx does not accept a pointer to const (in fact,
no function in lsxintrin.h does so), although it is not allowed
to modify the pointed-to buffer. Therefore this commit adds a wrapper
for it in order to constify the HEVC DSP functions in a later commit.
