arm/linux-yocto: move 6.1 patches to a unique bbappend

Move the 3 patches only needed by the 6.1 kernel into a unique bbappend
The defconfig changes cannot be moved into a config fragment because
they only exist in the defconfig file (because the patches that
integrated their functionality into the kernel were not merged).
