media: flexcop-i2c: Constify struct i2c_algorithm
'struct i2c_algorithm' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increase 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
6645 216 16 6877 1add drivers/media/common/b2c2/flexcop-i2c.o
After:
=====
text data bss dec hex filename
6721 160 16 6897 1af1 drivers/media/common/b2c2/flexcop-i2c.o
