[PATCH v1] crypto: Use named initializers for struct i2c_device_id

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Hello,

this patch is part of a bigger quest to use named initializers for
mainly struct i2c_device_id::driver_data to be able to modify
i2c_device_id. See e.g.
https://lore.kernel.org/all/20260518111203.639603-2-u.kleine-koenig@baylibre.com/
for the details.

This patch here isn't critical for this quest, as no driver makes use of
.driver_data, so apart from the better readability this is only about
consistency with other subsystems.

Best regards
Uwe
