Add mainline u-boot support

[hansemro]

Mainline u-boot status/tasks:

• [x] use new device model -> using FDT to configure drivers
• [ ] working SPL
• [x] working serial
• [ ] working I2C: untested
• [x] working SPI: omap3_dss
• [ ] working leds
• [ ] TWL6030 support + PWM
• [ ] SMB347 support
• [ ] TI BQ27541 support
• [x] working MMC: requires ti-clkctrl hack
• [x] clock control: There is a hack to get this working, but needs more testing
• [x] working GPTimer PWM driver
• [ ] working LCD panel/backlight: LCD requires power-up sequence via SPI which only works with omap4_spi drivers currently
• [x] working DSS Framebuffer
• [ ] working USB: controller not detected
• [x] successful kernel boot
• [ ] fastboot/dfu support
• [x] add OMAP USBBOOT command

Loading u-boot via usbboot

For now, I recommend loading u-boot via OMAP usbboot with omapboot tool. See here for steps to enter usbboot mode.

cd ..
git clone https://github.com/al177/omap4boot.git
git clone https://github.com/kousu/omapboot.git
cd omap4boot
make TOOLCHAIN=$CROSS_COMPILE
cp out/panda/aboot.bin ~/
cd ../omapboot
pip3 install --user pyusb
## install omapboot to ~/.local/bin:
python setup.py develop --user
export PATH=$PATH:~/.local/bin
cd ../kf_u-boot
## reboot kindle fire to usbboot mode, then run the command below
omapboot -a ~/aboot.bin u-boot.bin
