rcar: add h3-salvator-x instructions

Add the main build instructions for the H3-based Salvator-X board. Some
instructions are left out as the Salvator-X is under NDA, so I'm not
sure how many details we can provide.

 ### Update the firmware stack
 
-As an AArch64 platform both the **h3ulcb** and **m3ulcb** have a firmware stack that consists of multiple parts.  In both cases we have **ARM Trusted Firmware**, **OP-Tee** and **U-Boot** in use.  Starting with Eel you must update the firmware to at least the version referenced here.  For the exact steps required to flash the device see the eLinux.org wiki for **[h3ulcb][R-car h3ulcb firmware update]** or **[m3ulcb][R-car m3ulcb firmware update]** respectively.  In both cases the files listed in the table will be found in the *\$AGL_TOP/build/tmp/deploy/images/$MACHINE* directory as specified in previous steps.
