i2c: virtio: Constify struct i2c_algorithm and struct virtio_device_id
'struct i2c_algorithm' and 'struct virtio_device_id' are 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, which is the case for struct i2c_algorithm.
On a x86_64, with allmodconfig:
