This adds a driver to communicate with the APU available
in the mt8183. The driver is generic and could be used for other APU.
It mostly provides a userspace interface to send messages and
and share big buffers with the APU.

In order to reduce the memory mapping operations we are going to
add an IOCTL to request a mapping.
To make easier to add this new operation, use 2 lists to store the
mappings, one for the request and one for the device.

This adds the device tree node for the usb otg
controller present in the da850 family of SoC's.
This also enables the otg usb controller for the lcdk board.

Some macro for DA8xx CFGCHIP are defined in usb-davinci.h,
but da8xx-cfgchip.h intend to replace them.
The usb-da8xx.c is using both headers, causing redefined symbol warnings.
Remove the macro and update the board files to use da8xx-cfgchip.h

The first attempt to read a register may fail because the clock may not
be enabled, and then the probe of musb driver will fail.
Call clk_prepare_enable() before the first register read.

The purpose of this series is to add DT support to the da8xx USB OTG.
This series should apply and build without any issues but it has
some dependencies on "Add DT support for ohci-da8xx" series.
Without it, the phy init will fail and then the da8xx driver will also fail.
