ARM: shmobile: r8a7740: Prepare for reference DT setup
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 3b00f9342623a5ebc
"ARM: shmobile: sh73a0: Do not use early devices with DT reference"
