[PATCH 3.16 174/217] usb: dwc3: keystone: drop dma_mask configuration

[Ben Hutchings]

3.16.35-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Grygorii Strashko <grygorii.strashko@xxxxxx>

commit adf9a3ab90eb44e57f9dbf757acd897838b5ec21 upstream.

The Keystone 2 supports DT-boot only, as result dma_mask will be
always configured properly from DT -
of_platform_device_create_pdata()->of_dma_configure(). More over,
dwc3-keystone.c can be built as module and in this case it's unsafe to
assign local variable as dma_mask.

Hence, remove dma_mask configuration code.
