We need three steps to prepare for the new Armadillo reference DT board code:
 - Split the device list into r8a7740_early_devices used by the old platform
   data setup (board-armadillo.c) and r8a7740_devices_dt used by both
   setup variants.
 - Introduce new r8a7740_init_delay() to be more flexible about calling
   shmobile_setup_delay().
 - For the generic r8a7740 support, we switch to device tree setup for
   the GIC, the irqpin devices and the I2C controllers.

This is slightly similar to commit 3b00f934

Add generic DT board support for the r8a7740 SoC.

SCIF serial ports and timers are kept as regular
platform devices. Other on-chip and on-board devices
should be configured via the device tree.

At this point there is no interrupt controller support
in place but such code will be added over time when
proper IRQ domain support has been added to INTC.

Add generic DT board support for the sh7372 SoC V2.

SCIF serial ports and timers are kept as regular
platform devices. Other on-chip and on-board devices
should be configured via the device tree.

Tested on the mackerel board via kexec using a zImage
kernel with an appended dtb.

At this point there is no interrupt controller support
in place but such code will be added over time when
proper IRQ domain support has been added to INTC.
