[RFC PATCH 2/2] i2c: sh_mobile: drop needless check for of_node

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

After removal of platform_data support, we can simplify OF handling.
of_match_device() evaluates to NULL if !CONFIG_OF or if there is no node
pointer for that device, so we can remove the check for the node ptr.
