configs: fs.py can take multiple disk images on most ISAs
All ISAs except SPARC can now take multiple disk images by passing
the --disk-image option multiple times.
Before this patch, several ISAs automatically mounted a secondary disk
called "linux-bigswap2.img", which had to be in M5_PATH even if the end
user did not want more than one disk. This was the case for for example
for X86 but not ARM.
This change was done to:
* allow ARM to have a second disk image in fs.py, which was not possible,
and allow other ISAs like X86 and ARM to take any number of disk images
* provide a simpler, more intuitive CLI interface that does not require
magic disk images to be present in M5_PATH to work for ISAs such as X86.
Linux does not need that secondary image to boot correctly, so it is
more friendly to support a minimal setup that requires the least amount
of binaries to boot, and let supply the second image manually only if
they need it.
* make fs.py --disk-image work more similarly across all ISAs
SPARC was left with a single disk only because its setup was a bit more
complex and would require further testing.
