[PATCH] eeprom: at24: Use named initializers for arrays of i2c_device_data

[Uwe Kleine-König (The Capable Hub)]

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.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

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

Hello,

this patch was split from
https://lore.kernel.org/linux-kernel/20260515162734.469327-2-u.kleine-koenig@xxxxxxxxxxxx
on Bartosz's request. I'm not sure if still more should be split out, so
I'm not resending the remaining patch yet.

Best regards
Uwe
