Sergey Dyasli b95a72bb5b tools/xen-ucode: print information about currently loaded ucode 
Add an option to xen-ucode tool to print the currently loaded ucode
revision and also print it during usage info.  Print CPU signature and
platform flags as well.  The raw data comes from XENPF_get_cpu_version
and XENPF_get_ucode_revision platform ops.

Example output:
    Intel: CPU signature 06-55-04 (raw 0x00050654) pf 0x1 revision 0x02006e05
      AMD: CPU signature 19-01-01 (raw 0x00a00f11) revision 0x0a0011ce

Igor Druzhinin 25636ed707 tools/xen-ucode: return correct exit code on failed microcode update 
Otherwise it's difficult to know if operation failed inside the automation.

While at it, also switch to returning 1 and 2 instead of errno to avoid
incompatibilies between errno and special exit code numbers.
