It is follow up patch based on
"dm: Add support for all targets which requires MANUAL_RELOC"
(sha1: 484fdf5ba058b07be5ca82763aa2b72063540ef3)
to update function pointers for DM.

The current name is inconsistent with other driver model data access
functions. Rename it and fix up all users.

Only set the speed if it has changed from last time. Since the speed will
be 0 when the device is probed it will always be changed on the first
transfer after the device is probed.

These methods should be passed a slave device, not a bus. This matches the
old SPI interface. It is important to know which device is claiming the bus
so passing a bus is not that useful.

Add a convenience function to access the private data that a uclass stores
for each of its devices. Convert over most existing uses for consistency
and to provide an example for others.

At present we go through various contortions to store the SPI slave's chip
select in its private data. This only exists when the slave is active so
must be set up when it is probed. Until the device is probed we don't
actually know what chip select it will appear on.
However, now that we can support per-child platform data, we can use that
instead. This allows us to set up the chip select when the child is bound,
and avoid the messy contortions.
Unfortunately this is a fairly large change and it seems to be difficult to
break it down further.

At present we use struct spi_slave as our device pointer in a lot of places
to avoid changing the old SPI API. At some point this will go away.
But for now, it is better if the SPI uclass sets up this pointer, rather
than relying on passing it into the device when it is probed. We can use the
new uclass child_pre_probe() method to do this.

This is common to all SPI drivers and specifies a structure used by the
uclass. It makes more sense to define it in the uclass.

At present we try to use the 'reg' property and device tree aliases to give
devices a sequence number. The 'reg' property is often actually a memory
address, so the sequence numbers thus-obtained are not useful. It would be
better if the devices were just sequentially numbered in that case. In fact
neither I2C nor SPI use this feature, so drop it.
Some devices need us to look up an alias to number them within the uclass.
Add a flag to control this, so it is not done unless it is needed.
Adjust the tests to test this new behaviour.

The SPI function does the same thing, so we may as well just use the new
generic function. The 'cs' parameter was not actually used, so can be
dropped.

U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does. This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.
Many of references of those macros must be fixed to suppress warnings.
We have two options:
- Use min, max, min3, max3 only when the arguments have the same type
(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
argument

Add a uclass which provides access to SPI buses and includes operations
required by SPI.
For a time driver model will need to co-exist with the legacy SPI interface
so some parts of the header file are changed depending on which is in use.
The exports are adjusted also since some functions are not available with
driver model.
Boards must define CONFIG_DM_SPI to use driver model for SPI.
