[dts] [PATCH V2] add x86_x32 abi target support

[Haifeng Tang]

From: tanghaix <haifengx.tang at intel.com>

Support 32bit applications in 64bit mixed environments. x32 ABI (x32 application binary interface) is an application binary interface project for Linux kernel that allows programs to take advantage of the benefits of x86-64 (larger number of CPU registers, better floating-point performance, faster position-independent code shared libraries, function parameters passed via registers, faster syscall instruction) while using 32-bit pointers and thus avoiding the overhead of 64-bit pointers.
