Adding binman node with target images description can be unwanted feature
but as of today there is no way to disable it.
Also on size constrained systems it is not useful to add binman description
to DTB.
Introduce BINMAN_DTB Kconfig symbol which allows separate DTB for target
from DTB for binman itself.

Changes in v2:
- Change subject, align commit message
- binman - rename variable
- Use relative path
- Use separate variable in makefile to also handle empty string and default
to u-boot.dtb
