[OE-core] [PATCH oe-core v6] linux-dtb: add multi-dtb build support and keep dtb in deploy cache package

[Luo Zhenhua-B19537]

Saul, 

In this patch, dtb files are installed into ${D} and ${DEPLOYDIR} by kernel_do_deploy, there is a race issue of do_deploy and do_package.

"do_package" runs before dtb are installed into ${D}, so there is no dtb in /boot/devicetree/ and kernel-devicetree binary package is not generated due to empty content.

I will send out a patch to do ${D} install and ${DEPLOYDIR} install in separated steps: do_install and do_deploy. 


Best Regards,

Zhenhua
