ARM: Samsung: Add Exynos5422-based Odroid HC1 support

Browse Source 
Odroid HC1 board is based on Odroid XU4 board, but it has no HDMI,
no eMMC, no build-in USB3.0 hub, no extension port pins, and no GPIO
button. USB3.0 ports are used for build-in JMicron USB to SATA bridge
and Gigabit R8152 ethernet chips. HC1 uses only passive cooling.

This patch also updates Odroid's ADCmax array and reduces ADC tolerance
to 1% to ensure that XU4 and HC1 revisions are properly detected.

I've tested this with XU3, XU3-lite, XU4 and HC1 boards. In case of my test
boards I got following values from ADC register: 372, 370, 1281 and 1313.
