r8a7779 INTC needs IRL pin mode settings to determine
behavior of IRQ0 - IRQ3, and r8a7779_init_irq_extpin()
is controlling it via irlm parameter.
But this function registers renesas_intc_irqpin driver
if irlm was set, and this value depends on platform.
This is not good for DT.

a894fcc2 ("ARM: smp_twd: Divorce smp_twd
from local timer API") altered twd_local_timer_common_register() so that it
may make use of late_timer_init.

This is problematic on marzen with Magnus's recent patch "ARM: shmobile:
marzen: Switch to DT_MACHINE_START" which switches marzen around to enable
USE_OF and thus shmobile_timer_init(), which is registered as
late_time_init by shmobile_earlytimer_init() stops being a no-op.

As a work-around I have updated r8a7779_earlytimer_init() so that
shmobile_earlytimer_init() is called after r8a7779_register_twd().
Or in other words, the shmobile_earlytimer_init() setting of
late_time_init overwrites that of twd_local_timer_common_register().

Since we're now going to setup the USBPCTRL0 register using the USB PHY device's
platform data, we now need a way to pass those platform data from the board file
to the device which is situated in setup-r8a7779.c -- and what I'm suggesting is
r8a7779_add_usb_phy_device() that will register USB PHY platform device with the
passed platform data using platform_device_register_resndata() call; creating
this function involves deletion of 'usb_phy_device' from r8a7779_devices_dt[],
so that it will no longer be registered for the generic R8A7779 machine (where
we can't provide the platform data anyway), hence EHCI/OHCI drivers will fail
to load as well.

For the Marzen board, this new function will be called from marzen_init() to
register the USB PHY device early enough.

Note that the board and the SoC code have to be in one patch to keep the code
bisectable...

The patch has been tested on the Marzen board.

USB EHCI, OHCI, and common PHY are the SoC devices but are wrongly defined and
registered in the Marzen board file.  Move the data and code to their proper
place in setup-r8a7779.c; while at it, we have to rename r8a7779_late_devices[]
to r8a7779_standard_devices[] -- this seems legitimate since they are registered
from r8a7779_add_standard_devices() anyway.

Note that I'm deliberately changing the USB PHY platform device's 'id' field
from (previously just omitted) 0 to -1 as the device is a single of its kind.

Note also that the board and SoC code have to be in one patch to keep the code
bisectable...

Allow a minimal setup of the r8a7779 SoC using a flattened device tree.
In particular, configure the i2c and ethernet controllers using a
flattened device tree.

SCI serial controller and TMU clock source, whose drivers do not yet
support configuration using a flattened device tree, are still configured
using C code in order to allow booting of a board with this SoC.

The ethernet controller also requires a regulator which is a board property.
A sample snippet DT for the marzen board is as follows:

/dts-v1/;
/include/ "r8a7779.dtsi"

/ {
	fixedregulator3v3: fixedregulator@0 {
		compatible = "regulator-fixed";
		regulator-name = "fixed-3.3V";
		regulator-min-microvolt = <3300000>;
		regulator-max-microvolt = <3300000>;
		regulator-boot-on;
		regulator-always-on;

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
