Create librem5 board

Create an independent board for the Librem5 devkit.

The board code is copied from the Emcraft imx8m_som.

I would also prefer to not reuse the emcraft som for that. I've not tested this patch though.

Is there a reason not to name this board librem5-devkit instead of just librem5?

I'm getting the following error when using the librem5-base-defconfig:

  CFG     u-boot.cfg
In file included from ./include/common.h:21:
include/config.h:6:10: fatal error: configs/.h: No such file or directory

Bump. @Bonstra am I doing something wrong to compile this?

I was assuming the retail board would reuse most of the code from the devkit: we would keep the common code in imx8_som.c and put the sekeleton and device-specific code in new devkit.c and retail.c (or any other better name than "retail").

I'm getting the same error. I guess I didn't remove the .config before testing.

I had made a typo in the defconfig, should be fixed now…

I tested this, it works as advertised. @angus.ainslie or @guido.gunther do you agree?

Should this be librem5_devkit to distinguish it from the phone.

The idea was to avoid duplicating the board code again by having both librem5_devkit and librem5 (the final product) use the same board directory.

The common parts would be kept as is, while the non-common parts would be put into their own file, which would be included or not in the build by the Makefile depending on the TARGET_PURISM_LIBREM5_{DEVKIT,PHONE} config defines.

Though, given the relatively low amount of code in the board directory, maintaining the duplicated librem5 and librem5_devkit should still be manageable.

What do you all think is the best approach? Duplicate or keep everything in the same directory?
