8975cdf4bc sunxi: Make DRAM_ODT_EN Kconfig setting a bool
Make DRAM_ODT_EN Kconfig setting a bool, add a separate DRAM_ODT_CORRECTION
setting for A23 SoCs and use DRAM_ODT_EN Kconfig everywhere instead of
only in dram_sun4i.c and hardcoding odt_en elsewhere.

Note this commit makes no functional changes for existing boards,
its purpose is to allow changing the odt_en value on future A33 boards.

For sun4i/sun5i/sun7i boards which set DRAM_ODT_EN=y (which no defconfigs
currently do) this patch turns on odt for both the DQ and the DQS lines,
whereas previously it was possibly (but not desirable) to turn odt on only
for one of them by setting the in DRAM_ODT_EN option to 1 or 2 instead of 3.

8ffc487c75 sunxi: Stop differentiating between 512M and 1G variants of the same board
While working on adding more boards I noticed that we lack a config for
the 512M cubieboard, and that some of the new boards which I want to add also
have 512M and 1G variants, rather then adding 2 defconfig's for all of these,
lets switch the exising boards which have both a 512M and 1024M variant over
to the sun4i dram autoconfig code.

This also drops the foo_RAMSIZE_defconfig variants of boards where we currently
have 2 separate configs already.

Note:
1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with
a value other then its default for now, but we need this to be configurable
to support some new boards with auto dram config.

2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match
the defaults, this is done to make it more clear what values are used for a
certain board.

This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G
variants, the dram autoconfig code has also been tested on a 512M mk802
(a defconfig for the mk802 is added in a later patch).
