Now, all this driver does can be covered by the generic EHCI driver
(drivers/usb/host/ehci-generic.c).  UniPhier SoCs have switched to
use it.  Delete this driver rather than bothering to convert it to
Driver Model.

In current high speed fastboot, fs_ep_in.wMaxPacketSize is configured 64 bytes
as default, as a result, it failed to match the size at initialization stage in
usb controller.
Actually, hardware can support less than or equal to 512 bytes in high speed mode,
so I changed the condition from  '!=' to '>' to fix this issue.

This driver is designed in a generic manner, so clocks should be
handled genericly as well.

BUILD_BUG_* macros have been defined in several headers.  It would
be nice to collect them in include/linux/bug.h like Linux.

This commit is cherry-picking useful macros from include/linux/bug.h
of Linux 4.4.

I did not import BUILD_BUG_ON_MSG() because it would not work if it
is used with include/common.h in U-Boot.  I'd like to postpone it
until the root cause (the "error()" macro in include/common.h causes
the name conflict with "__attribute__((error()))") is fixed.
