Enable the checksum option for these two endpoints in order to allow
mobile data to actually work. Without this, no packets seem to make it
through the IPA.

In the downstream IPA driver there's only one group defined for source
and destination, and the destination group doesn't have a _DPL suffix.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/net after the previous
conversion commits apart from the wireless drivers to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_device from the private struct by converting it
into a pointer. Then use the leverage the new alloc_netdev_dummy()
helper to allocate and initialize dummy devices.

The only place ipa_version_supported() is called is in the probe
function.  The version comes from the match data.  Rather than
checking the version validity separately, just consider anything
that has match data to be supported.

In "ipa_cmd.h", ipa_cmd_data_valid() is declared, but that function
does not exist.  So delete that declaration.

Also, for some reason ipa_cmd_init() never gets called.  It isn't
really critical--it just validates that some memory offsets and a
size can be represented in some register fields, and they won't fail
with current data.  Regardless, call the function in ipa_probe().
