Basic codezero support for clcd device capability added.
...
1. We are not making a new clcd service container, as we dont want to keep
separate container for each device, ultimately we will have one
container managing all devices.
2. CLCD driver needs to be added.

KMI patch for devel branch on bahadir's repo.
...
Important points:
----------------
1. Works fine for pb926 + qemu.
2. Scan code logic for kryboard is not complete.
We just have generic keys and shift working.
3. Mouse scancodes are collected but not decoded.
4. Right now we are doing enable_irq(), just before we go for waiting
again for new irqs. This is not correct but we had latency issues.
This needs to be fixed immediately.
5. Also it seems like the notify_clot count should be an atomic
variable. Needs to be discussed.

Irqs are working. Scheduler modified to come back from no tasks.
...
- Userspace irq handling for timer.
- If no runnable task is left. scheduler busy loops in user context
of last runnable task until a new task becomes runnable.

thread to never wake up. Investigating.

Converted all wait/wakeup runqueue lock/unlock paths to irq versions.
...
Irqs can now touch runqueues and do async wakeups. This necessitated
that we implement all wake up wait and runqueue locking work with irqs.
All this, assumes that in an SMP setup we may have cross-cpu wake ups,
runqueue manipulation. If we later decide that we only wake up threads
in the current container, (and lock containers to cpus) we won't really
need spinlocks, or irq disabling anymore. The current set up might be
trivially less responsive, but is more flexible.

Reverted all changes - userspace devices mapped at initialization.
...
This is much simpler, no device map/unmap maintenance at run-time,
no lazy device mapping etc.

Made changes to map devices dynamically upon irq registration.
...
All will be reverted since mapping devices statically is much simpler.

Fixed false positive mmap return value error checks.
...
Normally a pointer with its topmost bits set may cause false errors
due to the fact that such pointers result in negative integer casts.
The remedy is to use IS_ERR() macro that accepts only down to -1000
as error and any values below as valid.
