This patch adds generic board, start of day and basic build system support for
the Allwinner A20 (sun7i) processor. This code will not been compiled until the
build is hooked up in a later patch. It has been split out to keep the patches
manageable.

v5: Based on 3f5ff92b1503 sunxi: add comments to pll1_para array.
- Correct SRAM_B/SRAM_D memory map
v4: Based on d9fe0a1e061e sunxi: mksunxiboot: remove unnecessary casts.
- No changes required
v3: Based on c89867dca2e9 sunxi: clocks: clock_get_pll5
prototype and coding style.
v2: Based on u-boot-sunxi.git#sunxi d9aa5dd3d15c sunxi: mmc:
checkpatch whitespace fixes with v2014.04-rc2 merged in:
- just init dram once
- remove clock ramping until power control is implemented
- add CONFIG_SUN7I to simplify future SUN?I support.
- fix a typo
v1: Based on u-boot-sunxi.git#sunxi commit d854c4de2f57 arm: Handle .gnu.hash
section in ldscripts vs v2014.01.
