doc: rockchip: puma: update build and flash instructions



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.

NOR-Flash
---------
Writing the SPI NOR Flash requires a running U-Boot. For the sake of simplicity
we assume you have a SD-Card with a partition containing the required files
ready.

rkdeveloptool allows to flash the on-board SPI via the USB OTG interface with
help of the Rockchip loader binary.
Reboot the system and you should see a U-Boot console on UART0 (115200n8).
