The Arm MPS3 FPGA prototyping board [0] have an isp1763 [1] as USB
controller.  There is already support for the isp1760 and isp1761 in
tree, this series extend the support also for the isp1763.

Move register access using regmap, remove some platform data and code,
refactor the mempool, use dr_mode to align to existing bindings, then
add the support for isp1763 host mode, add bindings files that did not
existed and at the end add also support for peripheral mode for
isp1763.

@Laurent and @Sebastian, I add both of you in the bindings files as
maintainers (it is a mandatory field)since you were the ones which
contributed with the initial code and peripheral code, let me know if
you are ok with it.  If yes I may send a follow up to add also entries
in MAINTAINERS file that it is also missing.

v1 [2] -> v2:

kernel test robot:
- add two patches (1/9 and 3/9) to fix dozens of pre-existing sparse
  warnings so that this series does not introduce new ones.
  No sparse warning left.
- fix duplication of regmap fields

Laurent:
- move initializers from .h to .c
- change interrupt registers setup from field to one shot register
  setting (did not change hcd hw mode init because I think it did not
  make the difference and even avoid artifact around setting twice the
  register)

Rob test bot:
- fix suffix at compatible string to clean up warning in bindings

Cheers,
   Rui
