Subject: [PATCH] ARM: exynos: defconfig update

This turns on a number of configs that are useful on the Chromebook, but also
good to have on in general:

* USB host and MMC drivers(!)
* I2C GPIO arbitration driver
* CYAPA trackpad driver
* simplefb
* CROS EC and keyboard drivers
* MAX77686 drivers
* DEVTMPFS + mount
* DM_CRYPT (as module)
* CRYPTOLOOP
* HIGHMEM
* PRINTK timestamps

This also turns off DEBUG_LL, and switches the hardcoded Samsung lowlevel
uart to uart 3 (which is only used to show the "uncompressing kernel"
message at boot, it seems).

(Note that the simplefb driver is still not merged up for 3.10, but it
hopefully will be).

Probably these aren't needed, but don't hurt since the default is 0.
This seems to pop up a lot since there are lots of legacy configs that
have 0x0 here.

Either with or without that fixup, this looks reasonable to me.

Setting the UART to 2, I tested this to work well with Arndale board.
Though, I would also like to enable S5M8767 driver (for Arndale board),
MAX8997 driver and MMC SDHCI driver (for Origen board). I will be
sending a patch to enable them.
