integration/soc/add_sdcard: Add an interrupt for command completion
...
This is useful for long-running commands generally and in particular
for those without any data transfer, such as erase. It is a
level-sensitive interrupt because that makes it a little harder to
lose interrupts due to incorrect programming.

Fix interrupt issue with ethernet on recent Linux-On-Litex-Vexriscv/SMP

software/liblitesdcard: Tell the controller when to wait while the card is busy
...
Bit 2 of the command register now tells the controller to wait while
the card is indicating that it is busy (by pulling the DAT0 line low).
The card can do this for commands 7 and 12 and app command 41 (and
also for commands 20, 28, 29, 38 and 43, but we don't use those here.)
This sets bit 2 for those commands.

It seems an overreaching 'interrupt-parent' caused trouble to interrupt routing.
This moves 'interrupt-parent' to the SoC entry.

The issue is that with no description provided it simply would
not put out a description tag, which breaks compatibility with
other programs.
Insert a somewhat useful default description including a timestamp
and the words "LiteX SoC".

use AutoDoc for timer documentation
...
Not sure why nobody else saw this, but sometime in the last month's
patches sphinx started throwing an error when building docs for
the timer block. The problem is that the body and title are 'None'
and the doc code tries to invoke methods on None.
Changing the doc methodology to AutoDoc and explicitly creating the intro
section fixes this.
