seabios: update to 1.9.1 stable release

git shortlog rel-1.9.0..rel-1.9.1
=================================

Cole Robinson (1):
      biostables: Support SMBIOS 2.6+ UUID format

Kevin O'Connor (7):
      xhci: Check for device disconnects during USB2 reset polling
      xhci: Wait for port enable even for USB3 devices
      sdcard: Only enable error_irq_enable for bits defined in SDHCI v1 spec
      sdcard: fix typo causing 32bit write to 16bit block_size field
      nmi: Don't try to switch onto extra stack in NMI handler
      scsi: Do not call printf() from scsi_is_ready()
      coreboot: Check for unaligned cbfs header

Marcel Apfelbaum (1):
      fw/pci: do not automatically allocate IO region for PCIe bridges

Roger Pau Monne (1):
      build: fix typo in buildversion.py
