[PATCH 1/5] i2c: mt65xx: drop of_match_ptr for ID table

[PATCH 1/5] i2c: mt65xx: drop of_match_ptr for ID table

[Krzysztof Kozlowski]

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might not be relevant here).
