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.

The memory region that is used by the driver overlaps EHCI and OHCI register
regions for absolutely no reason now -- fix it by adding offset of 0x800 to
the base address, changing the register #define's accordingly. This has extra
positive effect that we now can use devm_ioremap_resource()...
Note that the driver and the SoC code have to be in one patch to keep the code

Now that 'drivers/usb/phy/phy-rcar-usb.c' doesn't require the second memory

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...

This branch acts as a base for adding USB support to
r8A7778/BOCK-W and r8A7779/Marzen.
It includes the soc branch to provide dependencies in
the r8A7778 clock code.
It includes pinmux to provide pinmux initialisation for Bock-W
which is a dependency.

An earlier commit "ARM: shmobile: sh73a0: add support for adjusting CPU
frequency" intended to replace some clock operations only for the Z-clock,
instead it replaced them for all div4 clocks, since all div4 clocks share
the same copy of clock operations. Fix this by using a separate clock
operations structure for Z-clock.

Break out the function sh73a0_init_delay() that now
gets called both for the C version of the code and
the DT -reference boards. This way we handle both
cases in the same way.
Allows us to boot with TWD only in the kernel configuration
for C board code. TWD is not yet enabled in the case of
DT -reference - this due to a dependency on CCF.
