Documentation: replace install commands with softdeps

Install commands should not be used to specify soft dependencies among
modules. When loading modules it's much better to have a softdep that
modprobe knows what's being done than having to fork/exec another
instance of modprobe to load the other module.

By using a softdep user has also an option to remove the dependencies
when removing the module (and if its refcount dropped to 0)

In this case, the following can be added to config files in
/etc/modprobe.d/ as:
install bonding /sbin/modprobe tg3; /sbin/modprobe e1000;
/sbin/modprobe --ignore-install bonding
softdep bonding pre: tg3 e1000
This will load tg3 and e1000 modules before loading the bonding one.
Full documentation on this can be found in the modprobe.d and modprobe

the sound card. Installation dependencies must be written in configuration
files under /etc/modprobe.d/ directory:
install ad1848 /sbin/modprobe aedsp16 && /sbin/modprobe -i ad1848
install opl3 /sbin/modprobe aedsp16 && /sbin/modprobe -i opl3

Then you must load the sound modules stack in this order:
sound -> aedsp16 -> [ ad1848, opl3 ]
