[U-Boot] [PATCH 2/2] OMAP3: DTS: Cleanup omap3_logic DTS files from OMAP3 resync

[Adam Ford <aford173@gmail.com>]

logicpd-torpedo-som.dtsi is a direct port, but the
logicpd-torpedo-37xx-devkit is mostly copied from Linux, but
there are a few changes:

  Slow I2C1 to 400KHz from 26MHz, because U-Boot doesn't seem
   to handle that speed.

  Fixes required for U-Boot's NS16550 driver by adding
    reg-shift = <2> for each UART.

  Rename the model since this can booth both SOM-LV and Torpedo kits
   U-Boot will still load the proper dtb file from SD card for Linux

  Since there is only 1 support MMC socket on either dev kit,
   disable others in U-Boot

  Changes the license to SPDX
