To make 4k scsi devices to work, allocated memory needs to be increased
accordingly
Tested in the following scenario:
modprobe scsi_debug dev_size_mb=100 sector_size=4096
parted /dev/sdc u b p
Model: Linux scsi_debug (scsi)
Disk /dev/sdc: 209715200B
Sector size (logical/physical): 4096B/4096B
Partition Table: msdos
Number Start End Size Type File system Flags
1 262144B 2097151B 1835008B primary boot,
prep, type=41
2 2097152B 200015871B 197918720B primary type=83
qemu-system-ppc64 -enable-kvm -M pseries -m 1024 -nographic -drive
file=/dev/sdc,if=none,format=raw,id=drive-scsi0 -device
scsi-block,drive=drive-scsi0,id=scsi0 -vga none

Some folks put a whole zImage in there, and we can easily cope
with more than 8M nowadays.

This fixes booting from a path that has an explicitly specified
unit address on a wildcard node

The bootinfo.txt parsing code assumed that the filename to the boot loader
always contained a backslash. However, this is maybe not the case if the
boot loader has been put into the root directory of the filesystem. For example
SLES 8 used "boot &device;:1,yaboot.chrp" in its boot-script. Now we look for
the &device; string instead which should always work.
SLOF also failed if there were parameters after the path to the boot loader.
Now we take care of the parameters, too.

The parse-partition function was not able to deal with arguments that only
contained a partition number (without comma), e.g. "boot disk:1" failed.
Also limited the size that we load from a PReP partition in case the hard disk
is smaller than max-prep-partition-blocks.

The "offset" function only worked for partitions starting within the first
4 GiB of the disk.
Also increased the amount of data to be read from a PReP partition since some
clients are certainly bigger than 2 MiB nowadays.
