The WaRP7 has one mikroBUS socket on the back to plug click boards.
This patch allows to interact with some of these
i2c modules (EEPROM, RTC and so on).

nodes:
Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name
Converted using the following command:

This patch configures the board to output UART6 to the mikroBus.
The NXP WaRP7 board can route UART6 to the mikroBus, where an RS232
click board can be plugged in to get an additional serial port.

Currently the following eMMC error is seen:
mmc1: mmc_select_hs200 failed, error -74
mmc1: new MMC card at address 0001
mmcblk1: mmc1:0001 V10008 7.05 GiB
mmcblk1boot0: mmc1:0001 V10008 partition 1 4.00 MiB
mmcblk1boot1: mmc1:0001 V10008 partition 2 4.00 MiB
mmcblk1rpmb: mmc1:0001 V10008 partition 3 4.00 MiB
On imx7s-warp the eMMC VCCQ is fixed at 3.15V, so pass the 'no-1-8-v'
property to properly describe that 1.8V operation is not possible.
With this change HS200 error is gone and another benefit is that the
card can operate in DDR52 mode now:
mmc1: new DDR MMC card at address 0001

The i.MX7 has two iomux controllers. the iomuxc and the iomuxc_lpsr.
In a board dts we have to make sure that both controllers are supplied
with the correct pins. It's way too easy to do this wrong since only
a look into the reference manual can reveal which pins belong to which
controller. To make this clearer add "LPSR" to the pin names which
belong to the LPSR controller.
