Revert "staging: octeon: remove typedef in structs cvmx_pip_port_status_t and cvmx_pko_port_status_t"

This reverts commit b33a296d.

The patch series that removed typedefs from the octeon driver was not
actually built properly, and broke the build (it's hard to test-build
this driver for some reason.)  Remove them all at this point in time to
make sure the build works properly.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

The function fbtft_driver_remove_pdev() (that exists several times as it's
part of a macro expansion) returns zero unconditionally, so it can be
trivially converted to return void without semantic changes.

olpc_dcon is the only remaining i2c client device driver declaring
I2C_CLASS_DDC support after the legacy eeprom driver has been removed.

olpc_dcon is only used on olpc devices, connected to an i2c adapter
driven by scx200_acb. This adapter driver declares support for
I2C_CLASS_HWMON and I2C_CLASS_SPD. Therefore we can safely drop
I2C_CLASS_DDC support in olpc_dcon.

That's the last step before I2C_CLASS_DDC can be removed in general.

This patch is solely based on documentation, and I don't have an olpc
device for testing. Therefore some testing would be appreciated before
patch is applied.

to log trace messages using SRVTRACE_LEVEL. This is simply
moved to use the vchiq_log_debug() directly.
