Bug description:
  OpenSBI 0.9 backport to Focal

  [Impact]
  * OpenSBI is used to create RISC-V images for various boards and to boot RISC-V virtual machines.
   * Our current 0.8 release lacks a patch for CPU erratum CIP-1200 described in Errata_FU740-C000_20210205 from https://www.sifive.com/boards/hifive-unmatched
   * Bugs in OpenSBI that may lead to crashes have been resolved in v0.9.

  [Test Case]

   * Build U-Boot with new OpenSBI version and boot Focal images with
  this U-Boot installed.

  [Where problems could occur]

   * Parts of the OpenSBI code where restructured, new SBI extensions
  were added. Bugs in the modified code might lead to failure to boot,
  reboot, poweroff or might lead to crashes.

  [Other Info]

  Here are the release notes for OpenSBI Version 0.9:

  This release has:

  Lots of fixes and improvements
  Optimized trap handler for both RV32 and RV64
