Paul Gortmaker cdd24f76fe reset: lpc18xx: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/reset/Kconfig:config RESET_LPC18XX
drivers/reset/Kconfig:  bool "LPC18xx/43xx Reset Driver" if COMPILE_TEST
drivers/reset/Kconfig:  default ARCH_LPC18XX

or

arch/arm/Kconfig:config ARCH_LPC18XX
arch/arm/Kconfig:       bool "NXP LPC18xx/LPC43xx"

...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.

Joachim Eastwood 773fe72630 reset: lpc18xx: get rid of global variables for restart notifier
Moving the notifier_block into the drivers priv struct allows us
to retrive the priv struct with container_of and remove the
global variables.

Joachim Eastwood c392b65ba8 reset: add driver for lpc18xx rgu
Add reset driver for the Reset Generation Unit (RGU) found on NXP
LPC18xx and LPC43xx devies. This reset controller features up to 64
reset lines connected to different blocks and peripheral in the SoC.
Most reset lines on the controller are self clearing except for
those dealing with the Cortex-M0 cores on LPC43xx devices.

This driver also registers a restart handler that can be used to
reset the entire device.
