This allows just loading the kernel at a pre-set address without
qemu going bonkers trying to map the ELF file.
Contains a contribution from Aurabindo Jayamohanan to reuse the
PAGE_OFFSET definition.

Currently, there is only support for .gz compression type
for generating kernel Image.
Add support for other compression methods(lzma, lz4, lzo, bzip2)
that helps in generating a even smaller kernel image. Image.gz
will still be the default compressed image.

This patch extends Linux RISC-V build system to build and install:
Image - Flat uncompressed kernel image
Image.gz - Flat and GZip compressed kernel image
Quiet a few bootloaders (such as Uboot, UEFI, etc) are capable of
booting flat and compressed kernel images. In case of Uboot, booting
Image or Image.gz is achieved using bootm command.
The flat and uncompressed kernel image (i.e. Image) is very useful
in pre-silicon developent and testing because we can create back-door
HEX files for RAM on FPGAs from Image.
