board: theobroma-systems: add instructions for how to use upstream TF-A

Browse Source 
Upstream TF-A has support for RK3588 since v2.12 so let's document how
to use upstream TF-A instead of the prebuilt binary blob from Rockchip
if one wants to do that.

If using upstream TF-A, one should disable ``SPL_ATF_NO_PLATFORM_PARAM`` symbol in
U-Boot config (via e.g. ``make CROSS_COMPILE=aarch64-linux-gnu- menuconfig``) which
will, among other things, enable console output in TF-A.
This will build ``u-boot-rockchip.bin`` which can be written to an MMC device
(eMMC or SD card).
