The ene_ir driver was using a private define of MS_TO_NS, which is meant
to be microseconds to nanoseconds. The mceusb driver copied it,
intending to use is a milliseconds to microseconds. Lets move the
defines to a common location, expand and standardize them a touch, so
that we now have:
MS_TO_NS - milliseconds to nanoseconds
MS_TO_US - milliseconds to microseconds
US_TO_NS - microseconds to nanoseconds

Renamed has_new to is_new.
Drivers can use the is_new field to determine if a new value was specified
for a control. The v4l2_ctrl_handler_setup() must always set this to 1 since
the setup has to force a full update of all controls.

Some subdevs need to call into the board code after they are registered
and have a valid struct v4l2_device pointer. The s_config op was abused
for this, but now that it is removed we need a cleaner way of solving this.
So this patch adds a struct with internal ops that the v4l2 core can call.
Currently only two ops exist: register and unregister. Subdevs can implement
these to call the board code and pass it the v4l2_device pointer, which the
board code can then use to get access to the struct that embeds the
v4l2_device.
It is expected that in the future open and close ops will also be added.

The core.s_config op was meant for legacy drivers that needed to work with old
pre-2.6.26 kernels. This is no longer relevant. Unfortunately, this op was
incorrectly called from several drivers.
Replace those occurences with proper i2c_board_info structs and call
v4l2_i2c_new_subdev_board.
After these changes v4l2_i2c_new_subdev_cfg() was no longer used, so remove
that function as well.

There are several fields on rc_dev that drivers can benefit. Allow drivers
to pass it as a parameter to the driver.
For now, the rc_dev parameter is optional. If drivers don't pass it, create
them internally. However, the best is to create rc_dev inside the drivers,
in order to fill other fields, like open(), close(), driver_name, etc.
So, a latter patch making it mandatory and changing the caller drivers is
welcome.

This patch merges the ir_input_dev and ir_dev_props structs into a single
struct called rc_dev. The drivers and various functions in rc-core used
by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.
This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.
The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()

The only remaining drivers to depend on VIDEO_IR are bt8xx and
saa7134 (ir_rc5_timer_end is the only function exported by

This patch converts the cx88 driver (for sampling hw) to use the
decoders provided by ir-core instead of the separate ones provided
by ir-functions (and gets rid of those).
The value for MO_DDS_IO had a comment saying it corresponded to
a 4kHz samplerate. That comment was unfortunately misleading. The
actual samplerate was something like 3250Hz.
The current value has been derived by analyzing the elapsed time
between interrupts for different values (knowing that each interrupt
corresponds to 32 samples).
