doc: imx: Move SPD related info to the appropriate doc

Browse source 
Currently the Serial Download Protocol tools and procedure are
documented in two places:

- doc/imx/README.sdp
- doc/imx/README.imx6

It is better to consolidate all SDP related information into
README.sdp file, so move the content from README.imx6 to
README.sdp.

2. Using imx_usb_loader for first install with SPL
--------------------------------------------------
imx_usb_loader is a very nice tool by Boundary Devices that
allow to install U-Boot without a JTAG debugger, using
the USB boot mode as described in the manual. It is
a replacement for Freescale's MFGTOOLS.
The sources can be found here:
https://github.com/boundarydevices/imx_usb_loader.git
Booting in USB mode, the i.MX6 announces itself to the Linux Host as:
Bus 001 Device 111: ID 15a2:0061 Freescale Semiconductor, Inc.
imx_usb_loader is able to download a single file (u-boot.imx)
to the board. For boards without SPL support, it is enough to
issue the command:
sudo ../imx_usb_loader/imx_usb -v u-boot.imx
In order to load SPL and u-boot.img via imx_usb_loader tool,
please refer to doc/README.sdp.
