As per the ISP1761 data sheet, the DcChipID register represents
the hardware version number (0015h) and the chip ID (8210h) for the
Peripheral Controller.
This patch fixes the chip ID value used to verify the controller.

Hi Laurent,
I found that the chip ID is wrong when I tried testing OTG on vexpress
platforms. As per Section 10.8.2 DcChipID register in [1], it should be
0x00158210.
On the other hand, http://www.nxp.com/documents/data_sheet/SAF1761.pdf#120
uses 0x00011582. It looks like we need to accept both.
Thanks for sharing this datasheet, I will update to accept both ID and
resend.
Regards,
Sudeep
