Subject: [PATCH v2 0/3] irqchip: dw-apb-ictl: support hierarchy irq domain

v1 --> v2:
According to Marc Zyngier's suggestion, discard adding an independent SD5203-VIC
driver, but make the dw-apb-ictl irqchip driver to support hierarchy irq domain.
It was originally available only for secondary interrupt controller, now it can
also be used as primary interrupt controller. The related dt-bindings is updated
appropriately.

Add "Suggested-by: Marc Zyngier <maz@...nel.org>".
Add "Tested-by: Haoyu Lv <lvhaoyu@...wei.com>".

v1:
The interrupt controller of SD5203 SoC is VIC(vector interrupt controller), it's
based on Synopsys DesignWare APB interrupt controller (dw_apb_ictl) IP, but it
can not directly use dw_apb_ictl driver. The main reason is that VIC is used as
primary interrupt controller and dw_apb_ictl driver worked for secondary
interrupt controller. So add a new driver: "hisilicon,sd5203-vic".

  irqchip: dw-apb-ictl: support hierarchy irq domain
