mimxrt10xx: add 1050 support

[hierophect]

Continues off of #2918, adding support for the imx.RT 1052 EVK board. Fixes to this PR include adding the new reset register values (based on reference manual), never_reset flash pin protections, and an updated SDK submodule.

Currently not working - I don't believe the flash_config.c file is set up correctly. After loading the chip with a Jlink, the debugger reports a location that's partway into the program, not at the reset_handler as it should be. @arturo182 or @tannewt, do you have a sense for what could be going on with that?

[tannewt]

@hierophect My guess is that the flash data structures aren't correct and you are still in the ROM bootloader. You can use a logic analyzer on the SPI flash chip select line to see if code ends up being loaded off of it.

[hierophect]

@tannewt where could I find the configuration for that? On closer inspection of flash_config.c, it seems to be more or less identical across all the i.MX chips we support. I'll take a look at the SPI chip, but do you have a sense of which file I should be researching/tweaking to resolve the issue?

[tannewt]

@hierophect If you don't see more than a few reads to SPI flash, then I'd suggest reading the 9.7 Program Image section of the reference manual and triple checking both the image vector table and the device configuration data. I also wouldn't trust JLink's reset because the problem is so early in the boot process. Plugging and unplugging will be a pain but it'll assure you that you are starting from zero.

@sabas1080 were you successful in getting Circuitpython to load on the 1050 when you made your first PR?

Hi @hierophect

I have been away from this project, I plan to return in about 3 weeks, my last status I have not loaded circuitpython to the board

No biggie, I'm shelving this for now to work on some other things.

We're closing this for now because getting the dev kit going requires understanding hyperflash config. We'll reopen when ready to work on it again or create a new PR.
