The call to hash_block in passwd_abort fails with error ENOSPC on some

buffer to contain the computed hash does not get initialized.

This patch initializes the variable with the size of the buffer.

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.

The current environment has been hardcoded to an offset that starts to be
an issue given the current size of our main U-Boot binary.

By implementing a custom environment location routine, we can always favor
the FAT-based environment, and fallback to the MMC if we don't find
something in the FAT partition. We also implement the same order when
saving the environment, so that hopefully we can slowly migrate the users
over to FAT-based environment and away from the raw MMC one.

Eventually, and hopefully before we reach that limit again, we will have
most of our users using that setup, and we'll be able to retire the raw
environment, and gain more room for the U-Boot binary.
