Komeda driver uses a individual component to describe the HW's writeback
caps, but drivers doesn't define a new structure and still uses the
existing "struct komeda_layer" to describe this new component.
The detailed changes as follow:
1. Initialize wb_layer according to HW and report it to CORE.
2. CORE exposes wb_layer as a resource to KMS by private_obj.
3. Report writeback supporting by add a wb_connector to KMS, and then
wb_connector will take act as a component resources user,
so the func komeda_wb_encoder_atomic_check claims komeda resources
(scaler and wb_layer) accroding to its state configuration to the
wb_connector. and the wb_state configuration will be validated on the
specific component resources to see if the caps of component can
meet the requirement of wb_connector. if not check failed.
4. Update irq_handler to notify the completion of writeback.
NOTE:
This change doesn't add scaling writeback support, that support will
be added in the future after the scaler support.
v2: Rebase
v3: Rebase and constify the d71_wb_layer_funcs
v4: Addressed Ayan's comments

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5b
("kbuild: do not drop -I without parameter").

D71 consists of a number of Register Blocks, every Block controls a
specific HW function, every block has a common block_header to represent
its type and pipeline information.
GCU (Global Control Unit) is the first Block which describe the global
information of D71 HW, Like number of block contained and the number of
pipeline supported.
So the d71_enum_resources parsed GCU and create pipeline according
the GCU configuration, and then iterate and detect the blocks that
indicated by the GCU and block_header.
And this change also added two struct d71_dev/d71_pipeline to extend
komeda_dev/komeda_pipeline to add some d71 only members.
v2:
- Return the specific errno not -1.
- Use DRM_DEBUG as default debug msg printer.

Add komeda_kms abstracton to attach komeda_dev to DRM-KMS
CRTC: according to the komeda_pipeline
PLANE: according to komeda_layer (layer input pipeline)
PRIVATE_OBJS: komeda_pipeline/component all will be treat as private_objs
komeda_kms is for connecting DRM-KMS and komeda_dev, like reporting the
kms object properties according to the komeda_dev, and pass/convert KMS's
requirement to komeda_dev.

komeda_format_caps is for describing ARM display specific features and
limitations of a specific format, and format_caps will be linked into
&komeda_framebuffer like a extension of &drm_format_info.
And komed_format_caps_table will be initialized before the enum_resources,
since the layer features description depend on this format_caps table, so
we'd better initialize the table first.

Implement a simple wrapper for platform module to build komeda to module,
Also add a very simple D71 layer code to show how to discover a product.
Komeda driver direct bind the product ENTRY function xxx_identity to DT
compatible name like:
d71_product = {
.product_id = MALIDP_D71_PRODUCT_ID,
.identify = d71_identify,
},
const struct of_device_id komeda_of_match[] = {
{ .compatible = "arm,mali-d71", .data = &d71_product, },
{},
};
Then when linux found a matched DT node and call driver to probe, we can
easily get the of data, and call into the product to do the identify:
komeda_bind()
{
...
product = of_device_get_match_data(dev);
product->identify();
...
}
