down to SMP block. Having access to the cfg pointer here may create

MDP planes can be implemented using different type of HW pipes,
RGB/VIG/DMA pipes for MDP5 and RGB/VG/DMA pipes for MDP4. Each type
of pipe has different HW capabilities such as scaling, color space
conversion, decimation... Add a variable in plane data structure
to specify the difference of each plane which comes from mdp5_cfg data
and use it to differenciate the plane operation.

The maximum output width of one pipeline depends on the LayerMixer's
capability. It may be different on each target. Also, MDP5 doesn't
have vertical limitation in one frame, as long as the pixel clock
can be supported.
This change obtains the maximum LM resolution from configuration
table and treat it as the whole pipe's limitation for MDP5. The size
limit on MDP4 is not changed.

The current iteration in get_dsi_id_from_intf() is wrong:
instead of iterating until hw_cfg->intf.count, we need to iterate
until MDP5_INTF_NUM_MAX here.
Let's take the example of msm8x16:
hw_cfg->intf.count = 1
intfs[0] = INTF_Disabled
intfs[1] = INTF_DSI
If we stop iterating once i reaches hw_cfg->intf.count (== 1),
we will miss the test for intfs[1].
Actually, this hw_cfg->intf.count entry is quite confusing and is not
(or *should not be*) used anywhere else; let's remove it.

SMP blocks are configured for specific client IDs (ports).
These client IDs can be different from one chip to another for a
given pipe.
e.g.: DMA0 pipe fetch Y component is connected to:
- port #10 for MDP5 v1.3
- port #4 for MDP5 v1.6
In order to be compatible for upcoming versions of MDP5, the
client ID list is passed through the MDP5 config module rather
than using a list of hard-coded enum values.

MDP block is actually contained inside the MDSS block. For some
chipsets, the base address of the MDP registers is different from the
current (assumed) 0x100 offset.
Like CTL and LM blocks, this changes introduce a dynamic offset
for the MDP instance, which can be found out at runtime, once the
MDSS HW version is read.

Up until now, we assume that eDP is tight to intf_0 and HDMI to
intf_3. This information shall actually come from the mdp5_cfg
module since it can change from one chip to another.

Some interfaces (WB, DSI Command Mode) need to be kicked off
through a START Signal. This signal needs to be sent at the right
time and requests in some cases to keep track of the pipeline
status (eg: whether pipeline registers are flushed AND output WB
buffers are ready, in case of WB interface).

DSI and WB interfaces need a more complex pipeline configuration
than the current mdp5_ctl_set_intf().
For example, memory output connections need to be selected for
WB. Interface mode (Video vs. Command modes) also need to be
configured for DSI.
This change takes care of configuring the whole pipeline as far
as operation mode goes. DSI and WB interfaces will be added
later.

For example, use 'struct mdp5_smp *' everywhere instead of 'void *', but
only declare it as 'struct mdp5_smp;' in common headers, so the struct
body is still private. The accomplishes the desired modularity while
still letting the compiler provide some type checking for us.

The hardware configuration modification from a version to another
is quite consequent. Introducing a configuration module
(mdp5_cfg) may make things more clear and easier to access when a
new hardware version comes up.
