This patch is to add the fine grain tuning function for vangogh.
This function uses the pp_od_clk_voltage sysfs file to configure the min
and max value of gfx clock frequency or restore the default value.

Command guide:
echo "s level value" > pp_od_clk_voltage
        "s" - set the sclk frequency
        "level" - 0 or 1, "0" represents the min value,  "1" represents
        the max value
        "value" - the target value of sclk frequency, it should be
        limited in the safe range
echo "r" > pp_od_clk_voltage
	"r" - reset the sclk frequency, restore the default value
        instantly
echo "c" > pp_od_clk_voltage
        "c" - commit the min and max value of sclk frequency to the system
        only after the commit command, the setting target values by "s" command
        will take effect.
Example:
1)check the default sclk frequency
	$ cat pp_od_clk_voltage
	OD_SCLK:
	0:        200Mhz
	1:       1400Mhz
	OD_RANGE:
	SCLK:     200MHz       1400MHz
2)use "s" -- set command to configure the min or max sclk frequency
	$ echo "s 0 600" > pp_od_clk_voltage
	$ echo "s 1 1000" > pp_od_clk_voltage
	$ echo "c" > pp_od_clk_voltage
        $ cat pp_od_clk_voltage
	OD_SCLK:
	0:        600Mhz
	1:       1000Mhz
	OD_RANGE:
	SCLK:     200MHz       1400MHz
3)use "r" -- reset command to restore the min and max sclk frequency
	$ echo "r" > pp_od_clk_voltage
        $ cat pp_od_clk_voltage
	OD_SCLK:
	0:        200Mhz

Now that we actually expose the right number of planes we get
problems with modifier aware libva if we use an unsupported modifier.

So this ensures that we as much as possible use a modifier that
radeonsi can actually render to without going to extreme difficulty
to synchronize an extra DCC metadata plane with implicit sync.

Looking into the opaque metadata isn't ideal but this converts to
something mainly for the purpose of the userspace driver and falls
back properly if it isn't what we expect.

If we use DCC modifiers this can increase the number of planes from
the initial 1 plane with metadata, so that we get a valid modifier
from getfb2.

Since the code didn't update the format_info getfb2 would only ever
return 1 plane with a modifier for which userspace expects > 1.

This moves the format lookup to amdgpu_display.c so we do not have
issues when DC is not compiled.

Also do the proper validation which was missed.

Besides the missing validation, not storing the objects in the
framebuffer led to wrong results in the getfb2 ioctl.

Note that this should really have been done for multi-plane
formats like NV12 already before modifiers landed.

The table describes how each bit in the u64 value is used. Explicitly
state which values a field can take if we have defines for them. Also
add a note when a field isn't always populated.

Forcing people to update the table when changing the bit layout should
make it more obvious when there's a mistake, I hope.

If we get to the point where the bit layout gets more complicated, it
might be worth it to split the table into multiple tables (e.g. one for
GFX8, one for GFX9+, and so on).
