[U-Boot] [PATCH] x86: Add queensbay fsp patch information in README.x86
The FSP release version 001 for Intel Queensbay has a bug which could cause random endless loop during the FspInit call. This bug was published by Intel although Intel did not describe any details. Describe this information in the x86 doc so that U-Boot Queensbay support is invulnerable.
