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

  - [PATCH v9 1/8] support for fu740 cpu
  - [PATCH v9 2/8] support for fu740 clk driver
  - [PATCH v9 3/8] rename and support for fu740 ram driver
  - [PATCH v9 4/8] add pcie driver
  - [PATCH v9 5/8] dts for SiFive fu740
  - [PATCH v9 6/8] dts for SiFive Unmatched board
  - [PATCH v9 7/8] add Unmatched board support
  - [PATCH v9 8/8] clear feature disable CSR

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. Also based on pcie_dw_common.c
  - 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].
