[PATCH v2 dt-schema 2/3] schemas: i2c: clean up interrupt descriptions for I2C targets

[Wolfram Sang <wsa+renesas@sang-engineering.com>]

Schemas should be OS agnostic, so don't mention what the "I2C core" will
do because this only applies to Linux. Also, drop the generic
"smbus_alert" naming because this belongs to controllers not targets, so
we don't want to describe it here. Finally, use "contains" instead of
"items" because the enum is not exhaustive.
