[PATCH 00/19] sunxi: SPL cleanup part 1

[Andre Przywara]

This is the first part of a series to clean up the Allwinner SPL a bit.
One big driver for this whole clean up is to eventually accommodate the
RISC-V chips, which share most platform devices, but cannot use any code
that currently lives under arch/arm. So the idea is to disentangle the
code, to get a cleaner separation between ARM specific and platform
specific code. Another related reason is that the RISC-V port aims to
use a DM SPL, so we want to split off code bits that won't be needed when
we have the DM framework in the SPL.

This first part of the series is mostly preparation, and some smaller
cleanups, of code that was around for a long time and missed some
updates.
We start with some removal of no longer needed definitions, in the first
seven patches. The next seven patches tighten the SPL clock code: quite
some functions were compiled for U-Boot proper, however were not needed
there. Sorting this out helps to identify legacy code.
The final five patches move the SPL pinmux setup code into separate
functions and files, and convert the #ifdef hell into proper C "if"
statements.

It would be great if Samuel can have a look and say whether this is
helpful or not. For instance I don't really know how much of the SPL
clock code will be needed for the RISC-V port, since we don't really
model the bus clocks in the DT at all, and currently don't support PLLs
in the DM clock code.

Much of this first series should be good regardless, for instance the
replacement of #ifdef's with C "if" statements, since that became
tedious to expand for new SoCs and boards. But if some parts should live
in a different directory, or should be grouped differently, this can
certainly be factored in.

Please have a look, review and test!

Cheers,
Andre
