kernel-fitimage:fitimage_assemble() was calling copy_initramfs from
kernel.bbclass which decompresses the initramfs cpio.  Assume that if
INITRAMFS_FSTYPES includes a compressed cpio, that is what it desired in
the FIT image.

Check the value of UBOOT_SIGN_ENABLE, as it is defaulted to "0" which
for matches as True in python due to being a non-empty string.

The name of the output image for a fitImage that contains a ramdisk
should match the same as for the fitImage that does not contain a
ramdisk. As such it should not be assumed that KERNEL_IMAGETYPE is
"fitImage". This change explicitly sets the name of the output
ramdisk/initramfs to start with fitImage as does the non-ramdisk output.

Allow the load and entry addresses to remain unset if the UBOOT_RD_*
variables are also unset for ramdisk entries in the image tree. This
allows for U-Boot to decide dynamically where to load the ramdisk.

getVar() now defaults to expanding by default, thus remove the True
option from getVar() calls with a regex search and replace.

Search made with the following regex: getVar ?\(( ?[^,()]*), True\)

For x86, bzImage must be built instead of zImage.

Include setup.bin (which is required to boot the kernel) in the fitimage
and always use a load/boot address of 0x00090000.

If INITRAMFS_IMAGE is set, build an additional fitImage containing the
initramfs. Copy the additional fitImage and the source (*.its) file, used
to create it to DEPLOYDIR. The fitImage containing the initramfs must be
built before do_deploy and after do_install to avoid circular dependencies.

UBOOT_RD_LOADADDRESS - Specifies the load address used by u-boot for the
                       initramfs.
UBOOT_RD_ENTRYPOINT  - Specifies the entry point used by u-boot for the
                       initramfs.

Prior to assembling the fitimage, ensure that $B is the cwd due to
bitbake commit 67a7b8b021badc17d8fdf447c250e79d291e75f7 "build: don't
use $B as the default cwd for functions".

Without this change, do_assemble_fitimage() fails like:

Log data follows:
| DEBUG: Executing shell function do_assemble_fitimage
| arm-ka-linux-gnueabi-objcopy: 'vmlinux': No such file
| WARNING: exit code 1 from a shell command.

Add KERNEL_IMAGETYPES to support building packaging and installing
multi types of kernel images, such as zImage uImage, at one time.

KERNEL_IMAGETYPE and KERNEL_ALT_IMAGETYPE work as before.

The kernel fitImage must be amended with signature if and only if
UBOOT_SIGN_ENABLE = 1 . In the current case, the UBOOT_SIGN_ENABLE
could be either 0 (default) or 1 , which test -n always correctly
interprets as non-empty string, thus always true. This does not
match the logic above though, so replace the test with check which
passes only for UBOOT_SIGN_ENABLE = 1 .
