regulator: consumer: Reorder fields in 'struct regulator_bulk_data'

Browse Source 
Based on pahole, 2 holes can be combined in 'struct regulator_bulk_data'.

On x86_64 and allmodconfig, this shrinks the size of the structure from 32
to 24 bytes.

This is usually a win, because this structure is often used for static
global variables.

As an example:
Before:
   text	   data	    bss	    dec	    hex	filename
   3557	    162	      0	   3719	    e87	drivers/gpu/drm/msm/dsi/dsi_cfg.o

After:
   text	   data	    bss	    dec	    hex	filename
   3477	    162	      0	   3639	    e37	drivers/gpu/drm/msm/dsi/dsi_cfg.o
