[U-Boot] arm: suen3, suen3_v1, mgcoge2_arm_p1a support

[Heiko Schocher <hs@denx.de>]

This patch adds support for the Keymile SUEN3 board variants which
are based on the Marvell Kirkwood (88F6281) SoC. All variants
uses common code stored in board/keymile/km_arm/km_arm.c

mgcoge2_arm_p1a board:
This adds support for the ARM part of the mgcoge2. The suen3
target was moved to the correct suen3 p1b version. There is a
difference between the GPIO configuration between suen3 and mgcoge2.
