Support using u-boot with Image format for raspberrypi3-64

Browse Source 
For raspberrypi3-64 we need to use the Image or Image.gz format with u-boot
instead of the legacy uImage format. We also need to issue the 'booti' command
to boot the kernel instead of 'bootm'.

To have u-boot load kernel image, set in your local.conf:
KERNEL_IMAGETYPE = "uImage"
RPI_USE_U_BOOT = "1"
This will make kernel.img be u-boot image which will load uImage. By default,
kernel.img is the actual kernel image (ex. Image).
This will select the appropriate image format for use with u-boot automatically.
For further customisation the KERNEL_IMAGETYPE and KERNEL_BOOTCMD variables can
be overridden to select the exact kernel image type (eg. zImage) and u-boot
command (eg. bootz) to be used.
