The value of the RPI_KERNEL_VERSION can change between None and the
kernel version which can result in taskhash mismatch errors while
building images.
The taskhash mismatch errors can be reproduced using:
bitbake -c cleansstate virtual/kernel core-image-minimal && bitbake core-image-minimal
The get_dts() and split_overlays() functions are modified so that the
kernel version argument is optional. If the version is not supplied to
these functions, they will fallback to the Python equivalent of the
expression used for RPI_KERNEL_VERSION.

Kernel 4.4.6+ on RaspberryPi support .dtbo files for overlays, instead of .dtb.
Add support for both variants of overlays ("-overlay.dtb" and ".dtbo")
Change which variant needs to be supported based on the kernel version
CAUTION: when called from IMAGE_CMD_rpi-sdimg, 'TMPDIR' is not set, causing 'STAGING_KERNEL_BUILDDIR' to not be expanded, causing get_kernelversion_file() to fail!
To avoid this problem, get_dts() and split_overlays() MUST be called with the kernel version parameter set, when called from IMAGE_CMD_rpi-sdimg!

After '6392a63 rpi-base.inc: Use KERNEL_DEVICETREE by default' was
introduced, kernel versions < 3.18 might not be buildable. Since full
device tree support was introduced in 3.18 this change ensures that all
kernel < 3.18 will automatically disable device tree.
