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" Signed-off-by: Bastian Hecht <hechtb+renesas@gmail.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
