The USB host drivers need platform data to be defined on
pxa168 and pxa910, but the conditionals used in the devices.c
file only work if the drivers are built-in. This patch
fixes the definition by changing the #ifdef to #if IS_ENABLED(),
which works both for built-in and modular Kconfig symbols.
I found one specific problem using 'randconfig' builds, but
for consistency, this patch uses IS_ENABLED() for all Kconfig
symbols in these three files.

The ehci-mv can support PXA168, PXA910 and PXA920, use this driver to
support pxa168 SPH usb.

Add usb device support for Marvell PXA910.
Actually PXA920 will use the same device.

"""The Marvell® PXA168 processor is the first in a family of application
processors targeted at mass market opportunities in computing and consumer
devices. It balances high computing and multimedia performance with low
power consumption to support extended battery life, and includes a wealth
of integrated peripherals to reduce overall BOM cost .... """

1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core,
there are many enhancements like instructions for flushing the
whole D-cache, and so on
2. Clock reuses Russell's common clkdev, and added the basic support
for UART1/2.
3. Devices are a bit different from the 'mach-pxa' way, the platform
devices are now dynamically allocated only when necessary (i.e.
when pxa_register_device() is called). Description for each device
are stored in an array of 'struct pxa_device_desc'. Now that:
a. this array of device description is marked with __initdata and
can be freed up system is fully up
b. which means board code has to add all needed devices early in
his initializing function
c. platform specific data can now be marked as __initdata since
they are allocated and copied by platform_device_add_data()
4. only the basic UART1/2/3 are added, more devices will come later.
