To make boot.img smaller. With changes in pmaports!5544 we get a boot.img larger than the boot partition (8 MB). With these
changes we are down to around 7.8 MB, and hence have some margin again.
Noteable config changes:
Disable max14577/max77836 stuff, is only used by some Exynos 3 devices
Disable tps65090 driver and a few SND_SOC options that are only used by Exynos 5 devices
Tested on exynos4210-i9100 and exynos4412-m3, boots fine as long as rtc's and regulators are built-in. Still needs to be tested on
exynos4412-odroid-u2 and one of the tablets and note devices, so draft for now.
