This commit intends to implement "fixed-clock" as in Linux.
(drivers/clk/clk-fixed-rate.c in Linux)
If you need a very simple clock to just provide fixed clock rate
like a crystal oscillator, you do not have to write a new driver.
This driver can support it.

This command can use the bitmap display code in the uclass. This is similar
to the code in lcd.c and cfb_console.c. These other copies will go away when
all boards are converted to use driver model for video.

Sometimes the console must be rotated. Add a driver which supports rotating
the text clockwise to 90, 180 and 270 degrees. This can support devices
where the display is rotated for mechanical reasons.

Most of the time we don't need to rotate the display so a simple font
blitting feature is enough for our purposes. Add a simple driver which
supports this function. It provides text output on the console using
the standard 8x16-pixel font.

The existing LCD/video interface suffers from conflating the bitmap display
with text output on that display. As a result the implementation is more
complex than it needs to me.
We can support multiple text console drivers. Create a separate uclass to
support this, with its own API.

U-Boot has separate code for LCDs and 'video' devices. Both now use a
very similar API thanks to earlier work by Nikita Kiryanov. With the driver-
model conversion we should unify these into a single uclass.
Unfortunately there are different features supported by each. This
implementation provides for a common set of features which should serve
most purposes. The intent is to support:
- bitmap devices with 8, 16 and 32 bits per pixel
- text console wih white on black or vice versa
- rotated text console
- bitmap display (BMP format)
More can be added as additional boards are ported over to use driver model
for video.
The name 'video' is chosen for the uclass since it is more generic than LCD.
Another option would be 'display' but that would introduce a third concept
to U-Boot which seems like the wrong approach.
The existing LCD and video init functions are not needed now, so this uclass
makes no attempt to implement them.

A default invocation of sandbox U-Boot apparently uses no device tree,
which means that no timer is registers, which in turn means that the
sleep shell command hangs.
Fix the sandbox timer code to register a device when there's no DT, just
like e.g. the sandbox reset driver does. When there's no DT, the DM uclass
can't initialize clock_rate from DT, so set a default value in the
timer code instead.

At present the uclass's post_bind() method is called before the driver's
bind() method. This means that the uclass cannot use any of the information
set up by the driver. Move it later in the sequence to permit this.
This is an ordering change which is always fairly major in nature. The main
impact is that devices which have children will not see them appear in their
bind() method. From what I can see, existing drivers do not look at their
children in the bind() method, so this should be safe.
Conceptually this change seems to result in a 'more correct' ordering, since
the uclass (which is broader than the device) gets the last word.

At present we add driver-model MMC devices in the order we find them. The
'alias' order is not honoured.
It is difficult to fix this for the case where we have holes in the
sequence. But for the common case where the devices are numbered from 0
without any gaps, we can add the devices to the internal data structures
in this order.

pci_virt_to_mem() uses virt_to_phys() to get the physical address.
But pci_virt_to_mem() is also called with uncached addresses which
is wrong according to the documentation of virt_to_phys().
Refactor the PCI_TO_MEM() macro to optionally map an uncached address
back to a cached one before calling pci_virt_to_mem().
Currently pcnet works because virt_to_phys() is incorrectly implemented
on MIPS. With the upcoming asm header file update for MIPS, the
virt_to_phys() implementation will be fixed. Thus this patch is needed
to keep pcnet working on MIPS Malta board.
