[U-Boot] [PATCH 1/4] Add support for BeagleBoard.org PocketBeagle

Texas Instruments AM3358 based low-cost board using Octavo Systems OSD3358 SIP with built-in TPS65217 PMIC and 512MB DDR3. Board features small 35mm x 55mm size, high-speed USB OTG, microSD and 72 0.1" expansion header pins with 2xSPI, 2xI2C, 2xUART, USB, 8xADC, up-to-44 GPIO, PRU pins and much more.

https://beagleboard.org/pocket

This was tested using the am335x_evm_usbspl_defconfig.

Note that MII pins are enabled despite not having Ethernet on this board. This avoids an issue where otherwise many timeout errors would be generated. Seehttps://e2e.ti.com/support/arm/sitara_arm/f/791/t/298976 for some related discussion.
