From: Lucas Stach <dev@lynxeye.de>

This adds the description of the Nitrogen8 System on Module. The module
is quite simple with only a few (almost) fixed regulators and a eMMC
on-board.

The eMMC is currently limited to 50MHz modes via the pinctrl, as the board
has not wired up the data strobe line, which prevents HS400 mode from
working. As both the controller and the eMMC support this mode, it is
automatically selected when we allow the faster modes, leading to failing
transfers. Until we have a proper solution to only disable HS400 mode,
keep the eMMC at the slow bus modes.

v2:
- remove 100/200MHz pinctrl states for usdhc1
- rename i2c nodes

Just a nit: node names should be generic: rtc@68
