[COMMON] g2d: add request the job and schedule

This patch implements the life cycle of a task to G2D. A task has a
completion object to signal the user's request to let it know if its
requested task is completed.
All tasks are pushed to a workqueue that pushes tasks to H/W. It is
required for the tasks that have fences to wait because G2D driver
waits fences asynchronously Because the callback function called when
a fence is signaled is invoked under irq disabled. For the simplicity,
tasks without fences are also pushed to the workqueue because it does
not harm the responsibility to the users seriously.

Cho KyongHo [Fri, 21 Apr 2017 14:28:04 +0000 (23:28 +0900)]
[COMMON] g2d: add task management

G2D driver does not configure SFRs of G2D from the image processing
information from userspace. It just verifies a set of SFR values from
userspace and forwards to H/W the SFR values.
The possible number of SFR values is 830, and H/W limits the number to
1024, we have decided to maintain the pools of the buffers to store
the SFR values from userspace because allocation of 8KB at run-time
may consume a lot of time.
We also decided to create 16 buffers to store the SFR values which is
called 'Command list' because G2D H/W accepts 16 compositing jobs in
maximum.
We call entries in the pool as 'task' and a task has the following
elements:
- JOB ID that is used by H/W to distinguish jobs
- Descriptions of 16 source layers and the target image
- Buffer descriptions of each layer
- Command list

The life time of a task:
A new task is registered to tasks_free list of g2d_device. If a
compositing job is requested by userspace, G2D driver pulls a task
from tasks_free list and configures the task for the requested
compositing. When the configuration is finished, the task is
registered to tasks_prepared list. Therefore all tasks registered to
tasks_prepared are ready to be pushed to H/W. If a task should be wait
for fences to be signaled, it is not registered to tasks_prepared list
until the fence is signaled. As a result, tasks are listed in
tasks_prepared in a very short time except the system is falling into
suspend to RAM. The tasks remained in tasks_prepared are pushed to the
H/W as soon as the system is woken up from supend to RAM.
When H/W completes composting of a pushed task, it is removed from
tasks_active and returned to tasks_free.

The implemetation of the life cycle of tasks is included in the
following patch series.
