ARMv7: De-uboot-ify Exynos5250 code
When starting the Exynos5250 port, a lot of unneeded u-boot code was imported. This is an attempt to get rid of a lot of unneeded code before the port is used as a basis for further ARM ports. There is a lot more that can be done, including cleaning up the 5250's Kconfig file.

- * IO port access primitives
- * -------------------------
- *
- * The ARM doesn't have special IO access instructions; all IO is memory
- * mapped. Note that these are defined to perform little endian accesses
- * only. Their primary purpose is to access PCI and ISA peripherals.
- *
- * Note that for a big endian machine, this implies that the following
- * big endian mode connectivity is in place, as described by numerous
- * ARM documents:
- *
- * PCI: D0-D7 D8-D15 D16-D23 D24-D31
- * ARM: D24-D31 D16-D23 D8-D15 D0-D7
- *
- * The machine specific io.h include defines __io to translate an "IO"
- * address to a memory address.
- *
- * Note that we prevent GCC re-ordering or caching values in expressions
- * by introducing sequence points into the in*() definitions.
- *
- * The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space.
