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

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.

 The host side utilities are typically capable to interpret the i.MX
 specific image header (see doc/README.imximage). There are extensions
 for imx_loader's imx_usb utility which allow to interpret the U-Boot
 specific legacy image format (see mkimage(1)). Also the U-Boot side
 support beside the i.MX specific header the U-Boot legacy header.
