sdcard_image-rpi.bbclass: Allocate more space for boot partition
The boot partition currently has a size of 20 MiB but just the start elf binaries account almost 12 MiB, which means that only 8 MiB is left for the kernel image. A recent kernel with many of its options built-in can easily be more than 4 MiB so let's double the boot partition size to 40 MiB to make sure that it has enough room for the kernel image, the DTBs and possible even a backup kernel.
