sb/nvidia/mcp55: Fix P_state generation
amd_generate_powernow is never called by in lpc_slave_ops.
Move it to lpc_ops like on all other AMD southbridges.

commit 5374a30c33e10ee78478f06053410b534f49916f
Author: Iru Cai <mytbk920423(a)gmail.com>
Date: Sat Oct 29 23:37:42 2016 +0800
buildgcc: Update GCC, binutils, GMP and MPFR
- GCC gets updated from 5.2.0 to 6.2.0:
For RISC-V, I rebase riscv-gnu-toolchain on gcc-6_2_0-release and make a diff:
git diff --src-prefix=original-gcc/ --dst-prefix=gcc-6.2.0/ gcc-6_2_0-release
- Binutils goes from 2.26.1 to 2.27:
There is a build error for MIPS gold so I add patch for it.
The binutils RISC-V patch is generated with the following command when I have
official binutils git source and riscv-binutils-gdb (branch riscv-binutils-2.27
and rebase on binutils-2_27) in the same directory:
git diff --src-prefix=original-binutils/ --dst-prefix=binutils-2_27/ \
binutils-2_27 bfd gas binutils ld opcodes include/{*.h,elf,opcode}
- GMP gets a bump from 6.1.0 to 6.1.1
- MPFR is updated from 3.1.4 to 3.1.5
