This interrupt handler is broken in several ways:
- It loops forever when the op code is not decodeable
- It never returns IRQ_HANDLED because the only way to exit the loop
returns IRQ_NONE unconditionally.
The whole concept of this is broken. Creating devices in an interrupt
handler is beyond any point of sanity.
Make it at least behave halfways sane so accidental users do not have to
deal with a hard to debug lockup.

This driver is configured with a Kconfig option that is
declared as a bool. Hence it is not possible for the code
to be built as modular. However the code is currently using
the module_platform_driver() macro for driver registration.
While this currently works, we really don't want to be including
the module.h header in non-modular code, which we'll be forced
to do, pending some upcoming code relocation from init.h into
module.h. So we fix it now by using the non-modular equivalent.
And since we've already established that the code is non-modular,
we can completely drop any code relating to module_exit.

This is a bug fix that has been lurking in the Google tree but not pushed
upstream.
From: Octavian Purdila <octavian.purdila@intel.com>
The memory region is already reserved in goldfish_init() during
platform init.

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.
