Reset controller changes for v4.10

- remove obsolete STiH41[56] platform support
- add Oxford Semiconductor OX820 support
- add reset index include files for OX810SE and OX820
- make drivers with boolean Kconfig options explicitly
  non-modular
- allow shared pulsed resets via reset_control_reset, which
  in this case means that the reset must have been triggered
  once, but possibly earlier, after the function returns, and
  is never triggered again for the lifetime of the reset
  control

They allow configuration of memory interface and
bus priorities on the SoC to allow sufficient

Some SoCs (for example Amlogic GXBB) implement a reset controller which
only supports a reset pulse (triggered via reset_control_reset). At the
same time multiple devices (in case of the Amlogic GXBB SoC both USB
PHYs) are sharing the same reset line.

This patch allows using reset_control_reset also for shared resets.
There are limitations though:
reset_control_reset can only be used if reset_control_assert was not
used yet.
reset_control_assert can only be used if reset_control_reset was not
used yet.
For shared resets the reset is only triggered once for the lifetime of
the reset_control instance (the reset can be triggered again if all
consumers of that specific reset_control are gone, as the reset
framework will free the reset_control instance in that case).

The newly introduced pm_genpd_remove reverts the initialization done
by pm_genpd_init and is necessary in the error path of the rockchip
power-domain driver.

Without it the driver will in the error case cleanup the devm-allocated
structures including the elements referenced in the gpd_list thus making
deactivation of unused domains (and probably later genpd accesses as
well) fail by accessing invalid pointers.

drivers/reset/Kconfig:  bool "LPC18xx/43xx Reset Driver" if COMPILE_TEST
drivers/reset/Kconfig:  default ARCH_LPC18XX

or

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
