Build the imx code singing tool from source instead of relying on the
distro to provide the tool.
Use the debian/unstable branch because the default branch is outdated.
The binary is supposed to be build with docker, work around that by selecting
the correct Makefile directly.
Also append the description and add a link to documentation.

Add new binman etype which allows signing both the SPL and fitImage sections
of i.MX8M flash.bin using CST. There are multiple DT properties which govern
the signing process, nxp,loader-address is the only mandatory one which sets
the SPL signature start address without the imx8mimage header, this should be
SPL text base. The key material can be configured using optional DT properties
nxp,srk-table, nxp,csf-crt, nxp,img-crt, all of which default the key material
names generated by CST tool scripts. The nxp,unlock property can be used to
unlock CAAM access in SPL section.
