usb/host/r8a66597: remove conditional compilation of clk code
With addition of dummy clk_*() calls for non CONFIG_HAVE_CLK cases in
clk.h, there is no need to have clk code enclosed in #ifdef
CONFIG_HAVE_CLK, #endif macros.

usb: r8a66597-hcd: add function for external controller
R8A66597 has the pin of WR0 and WR1. So, if one write-pin of CPU
connects to the pins, we have to change the setting of FIFOSEL
register in the controller. If we don't change the setting,
the controller cannot send the data of odd length.

usb: r8a66597-hcd pio to mmio accessor conversion.
r8a66597-hcd is erroneously using PIO routines on MMIO registers, which
presently blows up for any platform that elects to either override or do
away with PIO routines. This managed to work for the common cases since
the PIO routines were simply wrapped to their MMIO counterparts. This
switches over to using the MMIO routines directly, and enables us to kill
off a lot of superfluous casting in the process.

usb: move r8a66597 register defines
Move r8a66597 hardware register definitions from the host
controller header file to the platform data header file.
With this change in place we can easily share register
definitions between the host controller driver and a future
gadget driver.

usb: r8a66597-hcd platform data on_chip support
Convert the r8a66597-hcd driver to use the on_chip flag
from platform data to enable on chip behaviour instead
of relying on CONFIG_SUPERH_ON_CHIP_R8A66597 ugliness.
This makes the code cleaner and also allows us to support
both external and internal r8a66597 with the same kernel.
It also makes the Kconfig part more future proof since
we with this patch can add support for new processors
with on-chip r8a66597 without modifying the Kconfig.

CPU/board specific parameters (PLL clock, vif etc...) can be set
by platform_data instead of module_param.
v2: remove irq_sense member in platform_data because it can OR in
IRQF_TRIGGER_LOW or IRQF_TRIGGER_FALLING against IORESOURCE_IRQ in

USB: r8a66597-hcd: host controller driver for R8A66597
I would like to submit Renesas R8A66597 USB HCD driver.
R8A66597 is Renesas USB 2.0 host and peripheral combined
controller device originally designed for embedded products.
As a limitation of this device, it does not support externel
hub more than 2 tier, and cannot communicate with a USB
device more than 10. Then this device is not compatible with
EHCI and/or OHCI, I wrote driver support patch based on
sl811 code.
This driver has the following unique specifications:
- Implement transfer timeout to share one pipe with plural endpoint.
- Detach detection of a USB device connected to externel hub.
The driver has been tested external hub, usb-hdd, usb-cdrom,
usb-speaker, mice, keyboard, and usbtest driver.
