runqemu: add QB_KERNEL_CMDLINE
runqemu auto generating the KERNEL_CMDLINE values and specifying using -append option to qemu boot command which will lead to override the kernel_cmdline/bootargs which are specified in DTB when using -dtb option. Add new macro QB_KERNEL_CMDLINE to specify not to add the runqemu generated KERNEL_CMDLINE values instead use which are in the DTB if value defined as 'none'. Add provision to override bootargs using # runqemu bootparams="root=/dev/ram0" (From OE-Core rev: 98f4bf980c378cc541b220d79ee006bf2fae9ae8) Signed-off-by: Raju Kumar Pothuraju <raju.kumar-pothuraju@xilinx.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
