usb/marvell: 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.

Marvell usb also has these dummy macros defined locally. Remove them as
they aren't required anymore.

USB: EHCI: Add Marvell Host Controller driver

This patch adds support for EHCI compliant HSUSB Host controller found
on Marvell Socs.

It fits both OTG and SPH controller on marvell Socs, including
PXA9xx/MMP2/MMP3/MGx.

usb: gadget: mv_udc: refine the driver structure

This patch do the following things:

1. Add header and Copyright for marvell usb driver.
2. Add mv_usb.h in include/linux/platform_data, make the driver
fits all the marvell platform using the same ChipIdea usb ip.
3. Some SOC may has mutiple clock sources, so let me define it
in mv_usb_platform_data and give two helper functions named
udc_clock_enable/udc_clock_disable to deal with the clocks.
4. Different SOCs will have some difference in PHY initialization,
so we will remove file mv_udc_phy.c and add two funtions in
mv_usb_platform_data, let the platform relative driver to realize it.
5. Rewrite probe function according to the modification list above. Find
it will kernel panic when probe failed. The root cause is as follows:
When probe failed, the error handle may call device_unregister()
which in return will call gadget_release.In current code,
gadget_release have two issues:
1: the_controller is a NULL pointer.
2: if we free udc here, then the following code in probe
will access NULL pointer.
