The dwc3_flush_cache() call was declared and used inconsistently:
* The declaration assumed 'int' for addresses (a potential issue
when running in a LP64 memory model).
* The invocation cast the address to 'long'.
This change ensures that both the declaration and usage of this
function consistently uses 'uintptr_t' for correct behaviour even
when the allocated buffers (to be flushed) reside outside of the
lower 32bits of memory.

dwc3 can do only max packet aligned transfers. So in case request length
is not max packet aligned and is bigger than DWC3_EP0_BOUNCE_SIZE
two chained TRBs is required to handle the transfer.

No functional change. Modified few things so that there are no
code duplication while implementing chained TRB.

In the linux kernel, non cacheable buffers are used. However in uboot
since there are no APIs to allocate non cacheable memory, all
the buffers should be flushed before using it.

Removed most of the trace_* APIs from dwc3 driver since tracepoints are not
supported in u-boot. Replaced some of the trace_* API with dev_dbg/dev/vdbg.

Modified the file header to the format that is used in u-boot. Also
included in the header, the commit in linux kernel from which each of
these files are added.

Added dwc3 folder from linux kernel 3.19-rc1 (97bf6af1f9)
to u-boot. This will be adapted to work with u-boot in the
following patches.
