When Gen3 support is added to the driver more than model ID will be
different for the different SoCs. To avoid a lot of if statements in the
code create a struct rvin_info to store this information.
While we are at it rename the poorly chosen enum which contains the
different model IDs from chip_id to model_id. Also sort the compatible
string entries and make use of of_device_get_match_data() which will
always work as the driver is DT only, so there's always a valid match.

In preparation for Gen3 support move the subdevice initialization and
clean up from rvin_v4l2_{register,unregister}() directly to the async
callbacks. This simplifies the addition of Gen3 support as the
rvin_v4l2_register() can be shared for both Gen2 and Gen3 while direct
subdevice control are only used on Gen2.
While moving this code drop a large comment which is copied from the
framework documentation and fold rvin_mbus_supported() into its only
caller. Also move the initialization and cleanup code to separate
functions to increase readability.

Document the devicetree bindings for the CSI-2 inputs available on Gen3.
There is a need to add a custom property 'renesas,id' and to define
which CSI-2 input is described in which endpoint under the port@1 node.
This information is needed since there are a set of predefined routes
between each VIN and CSI-2 block. This routing table will be kept
inside the driver but in order for it to act on it it must know which
VIN and CSI-2 is which.

The MCE keyboard sends both key down and key up events. We have a timeout
handler mce_kbd_rx_timeout() in case the keyup event is never received;
however, this may race with new key down events from occurring.
The race is that key down scancode arrives and key down events are
generated. The timeout handler races this and generates key up events
straight afterwards. Since the keyboard generates scancodes every 100ms,
most likely the keys will be repeated 100ms later, and now we have new
key down events and the user sees duplicate key presses.

In the past, "up" were an acronym for "user pointer" and "kp" for
"kernel pointer". However, since commit a1dfb4c48c ("media:
v4l2-compat-ioctl32.c: refactor compat ioctl32 logic"), both
are now __user pointers.
So, the usage of "kp" is really misleading there. So, rename
both to just "p32" and "p64" everywhere it occurs, in order to
make peace with this file's namespace.
There are two exceptions to "up/kp" nomenclature: at
alloc_userspace() and at do_video_ioctl().
There, a new userspace pointer were allocated, in order to store
the 64 bits version of the ioctl. Those were called as "up_native",
with is, IMHO, an even worse name, as "native" could mislead of
being the arguments that were filled from userspace. I almost
renamed it to just "p64", but, after thinking more about that,
it sounded better to call it as "new_p64", as this makes clearer
that this is the data structure that was allocated inside this
file in order to be used to pass/retrieve data when calling the
64-bit ready file->f_op->unlocked_ioctl() function.

Changeset dc9f65cf9a ("media: staging: atomisp: avoid a warning if 32

After a further analysis, this condition will always be false as, on
all architectures, size_t doesn't have more bits than unsigned long.
Also, the only two archs that really matter are x86 and x86_64, as this
driver doesn't build on other archs (as it depends on X86-specific UEFI
support).
So, just drop the useless code.
