board: Add new Samsung "stemmy" board based on ST-Ericsson U8500 The ST-Ericsson U8500 SoC has been used in mass-production for some Android smartphones released around 2012. In particular, Samsung has released more than 5 different smartphones based on U8500, e.g. - Samsung Galaxy S III mini (GT-I8190) "golden" - Samsung Galaxy S Advance (GT-I9070) "janice" - Samsung Galaxy Xcover 2 (GT-S7710) "skomer" and a few others. Mainline Linux has great support for the Ux500 SoC, so these smartphones can also run Linux mainline quite well. Unfortunately, the original Samsung bootloader used on these devices has limitations that prevent booting Linux mainline directly. It keeps the L2 cache enabled, which causes Linux to crash very early, shortly after decompressing the kernel. Using U-Boot allows to circumvent these limitations. We can let the Samsung bootloader chain-load U-Boot and U-Boot locks the L2 cache before booting into Linux. U-Boot has several other advantages - it supports device-trees directly and we are no longer limited to flashing Android boot images through Samsung's proprietary download mode. The Samsung "stemmy" board covers all Samsung devices based on U8500. Add minimal support for "stemmy". For now only UART is supported but this will be extended later.

board: stemmy: Update documentation Over the time, the "stemmy" U-Boot board was tested on several other Samsung smartphones based on ST-Ericsson NovaThor Ux500. Convert the documentation to reStructuredText at doc/board/ste/stemmy.rst and make the device list complete. Also note that the board now boots into USB Fastboot instead of just ending up at the U-Boot prompt. The device table is mostly taken from the postmarketOS wiki article (https://wiki.postmarketos.org/wiki/ST-Ericsson_NovaThor_U8500). All the newly added devices were tested by Linus Walleij.
