[PATCH v3 3/4] arm: dts: lpc32xx: reparent SIC1 and SIC2 interrupts from MIC

[Vladimir Zapolskiy]

The change adds separate device nodes for SIC1 and SIC2 interrupt
controllers and reparents all defined SIC1 and SIC2 interrupt
producers to the correspondent interrupt controller, this is needed to
perform switching to a new LPC32xx MIC/SIC interrupt controller driver.

Signed-off-by: Vladimir Zapolskiy <vz at mleia.com>
---
Changes from v2 to v3:
* fix io region size for MIC controller after moving SIC1/SIC2
  controllers out,
* move MIC 'reg' property up to follow 'compatible' property.

Changes from v1 to v2:
* squashed two step change in lpc32xx.dtsi - new irqchip driver can be
  used (i.e. board boots with access to userspace) with old DTS file,
  so there is no need to fix DTS firstly and then switch to a new driver,
* removed "interrupt-controller-name" and "wakeup-sources" properties
  from all interrupt controllers,
* removed outdated comment.
