[PATCH v2] drm/msm: Use nvmem_cell_read_variable_le_u32() to read speed bin

[Douglas Anderson]

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

The patch that this depends on is now in mainline so it can be merged
at will. I'm just sending this as a singleton patch to make it obvious
that there are no dependencies now.
