net: dsa: mv88e6xxx: Constify struct devlink_region_ops and struct mv88e6xxx_region
'struct devlink_region_ops' and 'struct mv88e6xxx_region' are not modified
in this driver.
Constifying these structures moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
18076 6496 64 24636 603c drivers/net/dsa/mv88e6xxx/devlink.o
After:
=====
text data bss dec hex filename
18652 5920 64 24636 603c drivers/net/dsa/mv88e6xxx/devlink.o
