The TF-A URL was updated, as a result the name of the
directory changed as part of the new git URL and not
all the referenced directories were updated.

The primary upstream URL for tf-a has moved, in some cases
things like tags are not always pushed to the old URL so
update the URLs to the primary upstream project URL.

Update and improve documentation about build steps for SoCs that
require using TF-A and TPL binaries provided by Rockchip, such as
rk3308. Add rk3308 boards case to rST document. Add ROCK Pi S in
the list of supported boards. Minor page format improvements.

Long gone is the time a custom TF-A was needed for Puma, upstream TF-A
works just fine now.

The flashing instructions are updated to match how newer rkdeveloptool
and rkbin work.

Finally, rkbin provides a way to flash SPI via USB OTG interface so
let's document that.

The ROC-RK3328-CC from Firefly and Libre Computer Project is a credit
card size development board based on the Rockchip RK3328 SoC, with:

  - 1/2/4 GB DDR4 DRAM
  - eMMC connector for optional module
  - micro SD card slot
  - 1 x USB 3.0 host port
  - 2 x USB 2.0 host port
  - 1 x USB 2.0 OTG port
  - HDMI video output
  - TRRS connector with audio and composite video output
  - gigabit Ethernet
  - consumer IR receiver
  - debug UART pins

The ROC-RK3328-CC has the enable pin of the SD card power switch tied
to GPIO_0_D6. This pin also has the function SDMMC0_PWREN, which is
muxed by default. SDMMC0_PWREN is an active high signal controlled by
the MMC controller, however the switch enable is active low, and
pulled low (enabled) by default to make things work on boot.

As such, we need to mux away from SDMMC0_PWREN and use GPIO to enable
power to the card. The default GPIO state for the pin is pull-down and
input, which doesn't require extra configuration when paired with the
external pull-down and active low switch.

Deal with this by enabling regulator support in SPL, and setting
"u-boot,dm-spl" for the regulator and other device nodes needed for
muxing the pin.

The device tree file is synced from the Linux kernel next-20200324.
