Convert the R8A7791 Porter board to DM and DT. This implies mostly enabling the necessary configuration options and plucking out the ad-hoc configuration from the board file. Moreover, the pre-reloc malloc size was increased to allow the clock driver to start up early without running out of malloc space and the early stack was moved further up in the DRAM to avoid rewriting U-Boot itself.
