drm/xe/pf: Fix documentation formatting

Current formatting of "The VF FLR Flow with GuC" only looks fine,
but it will not render properly when included in htmldocs due to:

  WARNING: Block quote ends without a blank line; unexpected unindent.
  CRITICAL: Missing matching underline for section title overline.

Fix that by adding proper indent and using list markup.

+ * The VF FLR flow includes several steps::
  *
- * Step 1: PCI HW generates interrupt to the GuC about VF FLR
- * Step 2: GuC FW sends G2H notification to the PF about VF FLR
- * Step 2a: on some platforms G2H is only received from root GuC
- * Step 3: PF sends H2G request to the GuC to start VF FLR sequence
- * Step 3a: on some platforms PF must send H2G to all other GuCs
- * Step 4: GuC FW performs VF FLR cleanups and notifies the PF when done
- * Step 5: PF performs VF FLR cleanups and notifies the GuC FW when finished
