regulator: bd9576: Constify struct linear_range
'struct linear_range' are not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.
This is also more consistent with the other struct linear_range declaration
above.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
20767 4544 0 25311 62df drivers/regulator/bd9576-regulator.o
After:
=====
text data bss dec hex filename
21023 4288 0 25311 62df drivers/regulator/bd9576-regulator.o
