[Intel-xe] [PATCH] drm/xe/xe-pci: print a message when probing a device

[Mauro Carvalho Chehab]

From: Mauro Carvalho Chehab <mchehab at kernel.org>

On devices with multiple GPUs, like:

	GPU device: ADLS, PCI ID: 8086:4680
	GPU device: DG2 (DG2_G12), PCI ID: 8086:56a3

Using force_probe parameter with a value different than "*" gives
a warning for the other GPU, like:

[  448.991536] xe 0000:00:02.0: Your graphics device 4680 is not officially supported
               by xe driver in this kernel version. To force Xe probe,
               use xe.force_probe='4680' and i915.force_probe='!4680'
               module parameters or CONFIG_DRM_XE_FORCE_PROBE='4680' and
               CONFIG_DRM_I915_FORCE_PROBE='!4680' configuration options.

This is confusing, as the subsequent messages refer to the
other probe attempt:

	[  448.991843] xe 0000:03:00.0: vgaarb: deactivate vga console
	[  449.007744] GT topology dss mask (geometry): 00000000,00ffff00
	[  449.007750] GT topology dss mask (compute):  00000000,00ffff00
	[  449.007752] GT topology EU mask per DSS:     0000ffff
	[  449.008846] xe 0000:03:00.0: [drm] vram_size: 0x180000000 usable_size: 0x17c800000
	[  449.008880] xe 0000:03:00.0: BAR 2: releasing [mem 0x6000000000-0x600fffffff 64bit pref]

Ok, one might infere from the PCI bus that it is for a different
card, but it is better to state so, as it helps debugging
issues and to check if the probe was really to the expected device.

So, prints the PCI ID of the GPU it will be about to probe.
