staging: comedi: addi_apci_3501: absorb i_APCI3501_Reset()

This driver only has one 'reset' function. Absorb the i_APCI3501_Reset()

Rename i_ADDI_Reset() to apci3501_reset() so that the function has

goldfish: add the goldfish virtual bus

This imports the current Google code and cleans it up slightly to use pr_ and
to properly request its resources.

Goldfish is an emulator used for Android development. It has a virtual bus where
the emulator passes platform device information to the guest which then creates
the appropriate devices.

This part of the emulation is not architecture specific so should not be hiding
in architecture trees as it does in the Google Android tree. The constants it
uses do depend on the platform and the platform creates the bus device which then
talks to the emulator to ascertain the actual devices present.

The original zcache in staging was a "demo" version, and this new zcache
is a significant rewrite.  While certain disagreements were being resolved,
both "old zcache" and "new zcache" needed to reside in the staging tree
simultaneously.  In order to minimize code change and churn, the newer
version of zcache was temporarily merged into the "ramster" staging driver
which, prior to that, had at one time heavily leveraged the older version
of zcache.  So, recently, "new zcache" resided in the ramster directory.

Got that? No? Sorry, temporary political compromises are rarely pretty.

The older version of zcache is no longer being maintained and has now
been removed from the staging tree.  So now the newer version of zcache
can rightfully reclaim sole possession of the name "zcache".

staging: comedi: introduce addi_watchdog driver

Many of the ADDI-DATA drivers have a "watchdog" subdevice that can
be used to monitor digital output activity. All the digital outputs
are released (set to 0) if the digital outputs are not accessed, or
the watchdog it not pinged, before the timeout of the watchdog
occurs. The only difference in the drivers for the watchdog subdevice
is the base address used to talk to the watchdog registers.

Instead of duplicating the code needed to support this watchdog,
introduce a helper module, similar to the 8255 module. This module
will be select'ed by the drivers that can use it.
