drm/xe/xe_survivability: Add support for survivability mode v2

Browse source

v2 survivability breadcrumbs introduces a new mode called
SPI Flash Descriptor Override mode (FDO). This is enabled by
PCODE when MEI itself fails and firmware cannot be updated via
MEI using igsc. This mode provides the ability to update
the firmware directly via SPI driver.

Xe KMD initializes the nvm aux driver if FDO mode is enabled.

Userspace should check FDO mode entry in survivability info sysfs before
using the SPI driver to update firmware.

	/sys/bus/pci/devices/<device>/survivability_info/fdo_mode

v2 also supports survivability mode for critical boot errors.
