This patch set is to add SiFive fu740 chip and HiFive Unmatched board
support. Patches are split into several parts:

  - [PATCH 1/7] dts for fu740
  - [PATCH 2/7] support for fu740 cpu
  - [PATCH 3/7- 4/7] support for fu740 clk and ram
  - [PATCH 5/7] add pcie driver
  - [PATCH 6/7] add unmatched board
  - [PATCH 7/7] add fu740 support to macb driver

Description

  - For fu740 cpu support, reuse most of fu540 cpu.
  - For prci driver, add one abstract layer to separate fu540 and
    fu740. Move orignal fu540 code to separate files.
  - For pcie driver, it depends on gpio, prci, clk and reset drivers
    to do init&reset works.
  - Align with Linux DT file.

Tests and patch checks

  - Able to boot both unmatched and unleashed boards.
  - PCIe tests
    . M.2 NVMe SSD
    . e1000 compatibale ethernet adapter (ping&tftpboot)
    . pci-to-usb adapter(usb mass storage)
  - checkpatch is performed. To keep code derived from other boards
    the same, ignore some warnings/errors in [PATCH 7/8].

Changlogs
  - V4
    . fixed incorrect file name in ./board/sifive/unmatched/Makefile

  - V2
    . Rebase to unleashed rename patch
    . remove unnessaary fu540 changes
    . split ram driver patch into 2 to keep 'git mv' info
    . use a shorter name for unmatched support
    . Remove redundant&incorrect temperature-sensor in DT
    . Remove unnecessary USB EHCI & OHCI from defconfig
    . Revised fu740 doc
    . Fixed year of copyright
