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
