[PATCH v4 00/14] Add Andes AE350 fdt driver support

[Yu Chien Peter Lin <peterlin@andestech.com>]

We move the devices used by AE350 to fdt driver framework, reuse
existing driver and add timer, ipi and reset drivers.
The OpenSBI domain support is also enabled. As of now, we can use
Kconfig to manage these configurations that can support variants of
Andes platform and SoC like Kendryte K510.

Changes v1 -> v2
  - Rename Andes-specific devices (PLMT, PLICSW) compatible string
  - Update ISA string in CPU nodes
Changes v2 -> v3
  - Add PATCH1 and PATCH2 to fix typos
  - Add PATCH3 which factors out a function for adding mtimer and ipi
    device regions to root domain
  - Remove unused variable "num_src" and "riscv,ndev" property of ipi 
    device node
Changes v3 -> v4
  - Add PATCH3 to fix grammar
  - Move plmt_{cold,warm}_timer_init() to andes_plmt.c and define
    fdt_plmt_cold_timer_init() which adds PLMT region and sets
    timer device
  - Move plicsw_{cold,warm}_ipi_init() to andes_plicsw.c and define
    fdt_plicsw_cold_ipi_init() which adds PLICSW region and sets
    ipi device
