Add support for the usb isp1760 host controller family, which
for example is present in MPS3 FPGA board from Arm (isp1763).

First we move some helper functions and defines to a more
common place to be shared by several urb users. (patch 1/3)

Then add the driver itself, is a ported version of the kernel
actual driver, which I am also the maintainer. (patch 2/3)

And last, enable it for the corstone1000 platform that uses
that MPS3 board for its implementation (patch 3/3).

Cheers,
   Rui

v3 -> v4:
    - rebase on top of next and resend with Marek in --to

v2[3] -> v3:
    - when you think you have amend commit and fix stay
      uncommitted.
      s/[HC_FIELD_MAX] = {};/[HC_FIELD_MAX] = {},/
v1[0] -> v2:
    - gentle ping
    - merge fix from kernel upstream [1]

PS: This should go on top of the corstone1000 platform enable
series [2]
