As there are no platforms for this SoC, remove the code.

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

Use XPL_ as the symbol to indicate an SPL build. This means that SPL_ is
no-longer set.

Use the new symbol to refer to any 'SPL' build, including TPL and VPL

This architecture and related board are unmaintained currently and have
been for a long time. Remove them.

This has been renamed to CONFIG_ARCH_RMOBILE but this one was left behind.
It doesn't point to a directory that exists, so just drop it.

The KONA and KONA_GPIO options don't exist anymore, since this commit:

   0f6807e77b0 arm: Remove bcm28155_ap board

Drop the dead code.

This converts the following to Kconfig:
   CONFIG_SKIP_LOWLEVEL_INIT
   CONFIG_SKIP_LOWLEVEL_INIT_ONLY

In order to do this, we need to introduce SPL and TPL variants of these
options so that we can clearly disable these options only in SPL in some
cases, and both instances in other cases.

Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01:
- SPL not supported yet --> no spl-dir in arch/arm/cpu/armv7/s5p4418/.
  Appropriate line in Makefile removed.
- cpu.c: '#include <cpu_func.h>' added.
- arch/arm/cpu/armv7/s5p4418/u-boot.lds removed, is not required
  anylonger.
- "obj-$(CONFIG_ARCH_NEXELL) += s5p-common/" added to
  arch/arm/cpu/armv7/Makefile since s5p-common/pwm.c is used instead
  of drivers/pwm/pwm-nexell.c.
- s5p4418.dtsi: '#include "../../../include/generated/autoconf.h"'
  removed, is not necessary, error at out-of-tree building.
  '#ifdef CONFIG_CPU_NXP4330'-blocks (2x) removed. Some minor changes
  regarding mmc. 'u-boot,dm-pre-reloc' added to dp0 because of added
  DM_VIDEO support.
- board/s5p4418/ renamed to board/friendlyarm/
- All s5p4418-boards except nanopi2 removed because there is no
  possibility to test the other boards.
- Kconfig: Changes to have a structure like mach-bcm283x (RaspberryPi),
  e.g. "config ..." entries moved from/to other Kconfig.
- "CONFIG_" removed from several s5p4418/nanopi2 specific defines
  because the appropriate values do not need to be configurable.
- nanopi2/board.c: All getenv(), getenv_ulong(), setenv() and saveenv()
  renamed to env_get(), env_get_ulong(), env_set() and env_save(),
  respectively. MACH_TYPE_S5P4418 is not defined anymore, therefore
  appropriate code removed (not necessary for DT-kernels).
- nanopi2/onewire.c: All crc8() renamed to crc8_ow() because crc8() is
  already defined in lib/crc8.c (with different parameters).
- dts: "nexell,s5pxx18-i2c" used instead of "i2c-gpio", i2c0 and
  i2c1 added. gmac-, ehci- and dwc2otg-entries removed because the
  appropriate functionality is not supported yet. New mmc-property
  "mmcboost" added.
  s5p4418-pinctrl.dtsi: gmac-entries removed, mmc- and i2c-entries
  added.
- '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where
  possible (and similar).
