Christophe JAILLET 5d55721d6e power: supply: samsung-sdi-battery: Constify struct power_supply_vbat_ri_table 
'struct power_supply_vbat_ri_table' are not modified in this driver.

Constifying these structures moves some data to a read-only section, so
increase overall security.

In order to do it, some code also needs to be adjusted to this new const
qualifier.

On a x86_64, with allmodconfig:
Before:
======
$ size drivers/power/supply/samsung-sdi-battery.o
   text	   data	    bss	    dec	    hex	filename
    955	   7664	      0	   8619	   21ab	drivers/power/supply/samsung-sdi-battery.o

After:
=====
$ size drivers/power/supply/samsung-sdi-battery.o
   text	   data	    bss	    dec	    hex	filename
   4055	   4584	      0	   8639	   21bf	drivers/power/supply/samsung-sdi-battery.o
