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]

Optimized trap handler for both RV32 and RV64
