Let's use the newly-added nvmem_cell_read_variable_le_u32() to future
proof ourselves a little bit.

This is based on my previous patch ("drm/msm: Fix speed-bin support
not to access outside valid memory") which has already landed in
msm-next. In case it's not obvious, this patch has a strong dependency
on my previous patch and also on patch #1 in this series.
