Commit Message

No user of the mt9p031_platform_data legacy platform data for board
files exist in the kernel anymore. Drop support from the driver.

we are not using CONFIG_OF anymore,  so i think we can just drop it.

The driver depends on OF but doesn't declare that depency in Kconfig,
hence the IS_ENABLED(CONFIG_OF). It can be dropped though, as
dev->of_node will be NULL in that case. I'll send a new version with the
check removed.
