[PATCH v2 00/13] v2: ARM: move lpc32xx to multiplatform

Version 2 contains some minor changes based on earlier feedback
and from the 0day build bot testing on other architectures. The
only patch that changed significantly is the one for the gpio driver.

I would suggest we merge this version into the soc tree directly
if there are no further concerns.

The lpc_eth driver uses a platform specific method to find
the internal sram. This prevents building it on other machines.

Rework to only use one function call and keep the other platform
internals where they belong. Ideally this would look up the
sram location from DT, but as this is a rarely used driver,
I want to keep the modifications to a minimum.

Setting the phy mode requires touching a platform specific
register, which prevents us from building the driver without
its header files.

Move it into a separate function in arch/arm/mach/lpc32xx
to hide the core registers from the network driver.

drivers/net/ethernet/nxp/lpc_eth.c:1316:31-32: WARNING comparing pointer to 0

 Compare pointer-typed values to NULL rather than 0

Semantic patch information:
 This makes an effort to choose between !x and x == NULL.  !x is used
 if it has previously been used with the function used to initialize x.
 This relies on type information.  More type information can be obtained
 using the option -all_includes and the option -I to specify an
 include path.

The lpc-enet driver can now be built on all platforms, so
allow compile testing as well.

Add one missing header inclusion that is required in some
configurations.
