Currently, the OpenSBI version is in top-level Makefile so
firmware linking to OpenSBI static library have no-way to
know OpenSBI version.
This patch moves OpenSBI version from top-level Makefile to
sbi/sbi_version.h header which provides OPENSBI_VERSION_MAJOR
and OPENSBI_VERSION_MINOR defines.
NOTE: the SBI spec (or SBI ecall interface) version is
different. The SBI spec version is provided by functions
sbi_ecall_version_major() and sbi_ecall_version_minor().

We don't need to install generic headers separately for every
platforn under <install_dir>/platform. It is unnecessary duplication
of files hence updating install_libplatsbi in top-level makefile.

Repeating "ifdef CROSS_COMPILE" multiple times does not help with
readability. Simplify by grouping compilation command setup under a
single ifdef statement.

Add rules to compile dts files into dtb files using the device tree
compiler (dtc). A platform can specify the DTS file to compile using
the platform-dtb-y variable. The flattened device tree binary file to be
used for building the final polatform firmware can be specified using
the new FW_PAYLOAD_FDT firmware configuration option to point to the
automatically compiled FDT file. Using the existing FW_PAYLOAD_FDT_PATH
configuration option is still possible and will take precedence over
the FW_PAYLOAD_FDT definition.

This patch extends top-level makefile to build and install
documentation. The 'docs' make target is for building the
documentation PDF whereas 'install_docs' make target is for
installing the documentation PDF.

The '?=' will not assign value if the target make variable is
overriden via command-line or is set in environment variable.
On other hand, '=' will not assign value only if variable is
overriden via command-line parameter.
It is quite common to have CC, AS, CPP, LD, etc to be set as
environment variables pointing to native compiler and binutils.
If '-rR' option is not set in MAKEFLAGS then this results in
compile error because '?=' will use the native compiler and
binutils. If '-rR' option is set in MAKEFLAGS then this again
results in compile error because CC, AS, CPP, etc are set to
empty strings which causes '?=' to use empty string as compiler
and binutils.
To handle this, we use '?=' only when CROSS_COMPILE is not
defined and we use '=' when CROSS_COMPILE is defined.

This improves 'clean' and 'distclean' makefile target as follows:
1. Remove only .o, .a, .elf, and .bin files for 'clean'
2. Remove .dep in-addition to what 'clean' does for 'distclean'
3. Remove default build and install directory for 'distclean'

We now have payloads sub-directory under firmware directory which
means payload BINs and ELFs should be installed under firmware/payloads.

The name CROSS_COMPILE is an industry standard used across
open-source project to specify cross-compiler prefix.
In fact, distro build systems such as buildroot and yocto
assume CROSS_COMPILE to be supported by projects added
as packages to these build systems.
This patch rename back CROSS_COMPILE_PREFIX to CROSS_COMPILE.
