renesas_usbhs driver can play role as both Host and Gadget.
In case of Gadget, it requires not only renesas_usbhs
but also usb gadget module (like g_ether).
So, renesas_usbhs driver calls usb_add_gadget_udc() on probe time.

Because of this behavior,
Host port plays also Gadget role if kernel has both Host/Gadget support.

In mackerel case, from 0ada2da5
(ARM: mach-shmobile: mackerel: use renesas_usbhs instead of r8a66597_hcd)
usb0 plays Gadget role, and usb1 plays Host role,
and current mackerel board probes as usb1 -> usb0.
Thus, 1st installed usb gadget module (like g_ether) will be
assigned to usb1 (= usb Host port), and 2nd module to usb0 (= usb Gadget port).
It is very confusable for user.
This patch fixup usb modes probing order as usb0 -> usb1.

Drivers for several devices on mackerel, including all SDHI instances, the
MMCIF controller and the SMSC9220 ethernet chip use regulators to control
power supply to their devices. MMC drivers need to be able to at least
retrieve voltage values from supplying regulators, whereas the smsc911x
driver only enables and disables chip power supplies without further looking
at them. This patch adds two fixed voltage regulators to describe 1.8V and
3.3V supplies on the board and a dummy regulator for SMSC9220.

Always use CS0 shadow area for NOR flash instead of regular CS0
memory area on Mackerel.

When booting from CS0 NOR Flash the regular CS0 memory area is
available, but when booting via USB the MASK ROM gets mapped to
0x0 which gets in the way for the NOR Flash. Always using CS0
shadow area works well for both NOR Flash boot and USB boot.

This change adds support for the sh7372 A4R power domain.

The sh7372 A4R hardware power domain contains the
SH CPU Core and a set of I/O devices including
multimedia accelerators and I2C controllers.

One special case about A4R is the INTCS interrupt
controller that needs to be saved and restored to
keep working as expected. Also the LCDC hardware
blocks are in a different hardware power domain
but have their IRQs routed only through INTCS. So
as long as LCDCs are active we cannot power down
INTCS because that would risk losing interrupts.
