binman: Add support for generating a FIT

FIT (Flat Image Tree) is the main image format used by U-Boot. In some
cases scripts are used to create FITs within the U-Boot build system. This
is not ideal for various reasons:

- Each architecture has its own slightly different script
- There are no tests
- Some are written in shell, some in Python

To help address this, add support for FIT generation to binman. This works
by putting the FIT source directly in the binman definition, with the
ability to adjust parameters, etc. The contents of each FIT image come
from sub-entries of the image, as is normal with binman.

mips: add config options for generic cache setup code

Add an own Kconfig symbol for the initial disabling of caches
invoked from generic start code.

Also add an own Kconfig symbols for the initialization of caches
invoked from generic start code.

Until now both code paths could only be disabled with
CONFIG_SKIP_LOWLEVEL_INIT. But this is not flexible enough for
RAM boot scenarios like EJTAG or SPL payload or for machines
which don't require cache initialization or which want to
provide their own cache implementation.

being referenced. This involves moving a pointer forward through the

through the word, but doesn't actually initialize it to point at the

fails since it sees the macro invocatoins's ( rather than the expected
alpha-numeric characters in the macro parameter. Fix this by adding the
