post: fix I2C POST failure for devices in CONFIG_SYS_POST_I2C_IGNORES
Devices in CONFIG_SYS_POST_I2C_IGNORES list may be absent and the rule is not to report I2C POST failure for devices in this list. Currently this doesn't work since probing for these devices isn't done and thus they are not marked as successfully probed. Ignore optional devices when checking for devices that didn't respond.
