Add support for creating an Amlogic Boot Image that pass CHK in BL1 on
Amlogic AArch64 SoCs.

Images can optionally be signed for secure boot scenario, however
creation of signed images has not been implemented.

Example of how to use it:
# Create an amlogic boot image
tools/mkimage -T amlimage -n gxbb -d u-boot-spl.bin u-boot-amlogic.bin

# List boot image header information
tools/mkimage -l u-boot-amlogic.bin

# Extract amlogic boot image payload
tools/dumpimage -T amlimage -o bl2-payload.bin u-boot-amlogic.bin

Or with binman using something like:
binman {
u-boot-amlogic {
filename = "u-boot-amlogic.bin";
pad-byte = <0xff>;

mkimage {
filename = "bl2.bin";
args = "-n", "gxbb", "-T", "amlimage";

u-boot-spl {
};
};
};
};
