On some GPUs the PCIe atomic requirement for KFD depends on the MEC
firmware version. Add a firmware version check for this. The minimum
firmware version that works without atomics can be updated in the
device_info structure for each GPU type.

Move PCIe atomic detection from kgd2kfd_probe into kgd2kfd_device_init
because the MEC firmware is not loaded yet at the probe stage.

Add manual sclk/vddc setting supoort via pp_od_clk_voltage sysfs
to maintain consistency with other asics. As cyan skillfish doesn't
support DPM, there is only a single frequency and voltage to adjust.

v2: maintain consistency and add command guide.
v3: adjust user settings storage and coding style.

Command guide:
echo vc point sclk vddc > pp_od_clk_voltage
	"vc"    - sclk voltage curve
	"point" - must be 0
	"sclk"  - target value of sclk(MHz), should be in safe range
	"vddc"  - target value of vddc(mV), a 6.25(mV) stepping is
		  recommended and should be in safe range (the real
		  vddc is an approximation of target value)
echo c > pp_od_clk_voltage
	"c"	- commit the changes of sclk and vddc, only after
		  the commit command, the target values set by "vc"
		  command will take effect
echo r > pp_od_clk_voltage
	"r" 	- reset sclk and vddc to default value, a subsequent
		  commit command is needed to take effect

Example:
1) Check default sclk and vddc
	$ cat pp_od_clk_voltage
	OD_SCLK:
	0: 1800Mhz *
	OD_VDDC:
	0: 862mV *
	OD_RANGE:
	SCLK:    1000Mhz       2000Mhz
	VDDC:     700mV        1129mV
2) Set sclk to 1500MHz and vddc to 700mV
	$ echo vc 0 1500 700 > pp_od_clk_voltage
	$ echo c > pp_od_clk_voltage
	$ cat pp_od_clk_voltage
	OD_SCLK:
	0: 1500Mhz *
	OD_VDDC:
	0: 693mV *
	OD_RANGE:
	SCLK:    1000Mhz       2000Mhz
	VDDC:     700mV        1129mV
3) Reset sclk and vddc to default
	$ echo r > pp_od_clk_voltage
	$ echo c > pp_od_clk_voltage
	$ cat pp_od_clk_voltage
	OD_SCLK:
	0: 1800Mhz *
	OD_VDDC:
	0: 874mV *
	OD_RANGE:
	SCLK:    1000Mhz       2000Mhz
	VDDC:     700mV        1129mV
NOTE:
We don't specify an explicit safe range, you can set any values
between min and max at your own risk. Enjoy!

In amdgpu_dm_atomic_check, dc_validate_global_state is called. On
failure this logs a warning to the kernel journal. However warnings
shouldn't be used for atomic test-only commit failures: user-space
might be perfoming a lot of atomic test-only commits to find the
best hardware configuration.

Downgrade the log to a regular DRM atomic message. While at it, use
the new device-aware logging infrastructure.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.

So, refactor the code a bit to use the purpose specific kcalloc()
function instead of the calculated size argument in the kzalloc()
function.
