Some of the ldo-s of the axp221 are used in the same way on most boards, add
comments to the Kconfig help text to reflect this, and give them defaults
matching their typical usage.

The Colombus defconfig settings are missing a number of settings for recently
added features, because we did not know exactly how things were hooked up.

Maxime Ripard has run various tests to get us the necessary details, this
commit updates the defconfig with this info.

This commit also updates the dram clk and zq values with values verified
by Maxime to be the ones used by the original firmware for this board.

It turns out that there is a too large spread between boards to handle this
with a default value, turn this into Kconfig options, and set the values
the factory images are using for the Colombus and Mele_M9 boards.

Note this changes the ZQ default when not overriden through defconfig from
120 to 123, as that is what most boards seem to actually use.

This was done automatically with the following bits of scripting.

The Kconfig choice content was generated with this script snippet:
    for i in $(git grep -l CONFIG_ARCH_SUNXI configs/*) ; do
        TARGET=$(sed -n -e 's/CONFIG_SYS_EXTRA_OPTIONS="\([^,"]\+\).*/\1/p' $i);
        MACH=$(sed -n -e 's/.*CONFIG_\(MACH_SUN.I\)=./\1/p' $i)
        echo "config TARGET_$TARGET"
        echo "	bool \"$TARGET\""
        echo "	depends on $MACH"
        echo
    done

defconfigs were updated with a sed script (t):
    # Extract board from first entry of CONFIG_SYS_EXTRA_OPTIONS,
    /^CONFIG_SYS_EXTRA_OPTIONS/ {
        s/^\(CONFIG_SYS_EXTRA_OPTIONS="\)\([^,"]\+\),\?\(.*\)/\1\3\nCONFIG_TARGET_\2=y/;

        # Print and delete first line (CONFIG_SYS_EXTRA_OPTIONS), leaving
        # CONFIG_TARGET_<BOARD> in pattern space
        P;D;
    };

    # Move CONFIG_TARGET_<BOARD> to hold space
    /^CONFIG_TARGET/{h;n}

    # Print CONFIG_TARGET_<BOARD> after CONFIG_MACH_<SOC> in either SPL or
    # normal mode.
    /^CONFIG_MACH/{p;g;p;n};
    /^\+S:CONFIG_MACH/{p;g;s/^CONFIG_TARGET/+S:&/;p;n};

    # Print any remaining lines normally
    p;
Run as:
    sed -i -n -f t $(git grep -l CONFIG_ARCH_SUNXI configs/*)
and then manually removing the one instance of CONFIG_SYS_EXTRA_OPTIONS="" from
Colombus_defconfig

board/sunxi/Makefile was updated with:
    sed -e 's/^\(obj-\$(CONFIG_\)\(.*\)\().*+= dram_.*\)/\1TARGET_\2\3/g' board/sunxi/Makefile
and manually retabbing a few lines to line up again.

The board descriptions could certainly be improved.

Now we have CONFIG_ARCH_SUNXI as the toplevel, CONFIG_MACH_SUN[45678]I as the
per-SoC option and leave CONFIG_TARGET_BLAH free for individual boards in the
future.

The Colombus board is an A31 evaluation board from WITS Technology.

Maxime has kindly agreed to maintain this board.
