We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts psxpad-spi driver to use the
polling mode of standard input devices and removes dependency on
INPUT_POLLDEV.

static const. Makes the object code smaller by 30 bytes.

This patch adds support for the FlySky FS-iA6B RC receiver (serial IBUS).
It allows the usage of the FlySky FS-i6 and other AFHDS compliant remote
controls as a joystick input device.
To use it, a patch to inputattach which adds the FS-iA6B as a 115200 baud
serial device is required. I will upstream it after this patch is merged.

USB transport has to use cache line-aligned buffers for transfers to avoid
DMA issues; serio doe snot have such restrictions. Let's move "data_in"
buffer from main driver structure into transport modules and make sure USB
requirements are respected.

We want to move buffer handling into transport layers as the properties of
buffers (DMA-safety, alignment, etc) are different for different
transports. To allow this, let's allow caller to specify their own buffers
for the results of iforce_get_id_packet() and let transport drivers to
figure what buffers they need to use for transfers.

It is excessive to check if device is fully initialized in
iforce_process_packet(), as for USB-conected devices we do not start
collecting reports until the device is fully initialized.
Let's change serio transport code to not call iforce_process_packet()
until device initialization is done.

Signalling command completion from iforce_process_packet() does
not make sense, as not all transport use the same data path for
both commands and motion data form the device, that is why USB
code already has to signal command completion iforce_usb_out().
Let's move signalling completion into individual transport
modules.

Current code combines packet type and data length into single argument to
iforce_process_packet() and then has to untangle it. It is much clearer to
simply use separate arguments.

When working with USB devices we need to use DMA-safe buffers,
and iforce->edata is not one. Let's rework the code to allocate
temporary buffer (iforce_get_id() is called only during initialization
so there is no reason to have permanent buffer) and use it. While at it,
let's utilize usb_control_msg() API which simplifies code.
