- Update MPC83xx platform support to current best practices, etc.

"Please pull mmc-5-20 for v2019.07, this is to avoid break i.MX53 boot."

- update for using splashfile instead of location->name
  when loading the splash image from a FIT
- updates for loading internal and external splash data from FIT
- DM_GPIO/DM_VIDEO migration for mx53 cx9020 board
- fix boot issue on mx6sabresd board after DM_VIDEO migration
- increase the max preallocated framebuffer BPP to 32 in ipuv3
  driver to prepare for configurations with higher color depth
- allow to use vidconsole_put_string() in board code for text
  output on LCD displays

The gdsys gazerbeam board is based on a Freescale MPC8308 SOC.
It boots from NOR-Flash, kernel and rootfs are stored on
SD-Card.

On board peripherals include:
- 2x 10/100 Mbit/s Ethernet (optional)

The ppc4xx architecture was removed, and with it several old gdsys 44x

Some DM drivers have hardcoded clk_enable calls when handling

To support OF_EMBED, the MPC83xx architecture has to define the "_end"
symbol to correctly access the appended DT.

Fortunately, MPC8xx already defines the symbol, and the linker script is
quite similar to that of MPC83xx, so copy this approach for MPC83xx.

Lots of stuff in processor.h was taken verbatim from the Linux kernel.
It was never synced, so most of it was removed or changed in the kernel
since it was imported.

Remove all the stuff that is unused in the current U-Boot sources;
should anybody feel the need to re-sync with the kernel, they can do it
later on.

For a lot of inline assembly calls in the mpc8xxx and mpc83xx
directories, we already have convenient pre-defined helper functions,
but they're not used, resulting in hard-to-read code.

ppcDWstore/ppcDWload are hardly used by any board, but since they're
implemented in start.S, they're always present in every U-Boot image,
even if they're not needed.

Re-implement these fuctions in C with inline assembly, so that the
compiler can decide when to actually include them.

Except for one counter example, CONFIG_SYS_LBC_LBCR always has a value
of either 0x00040000 or 0x00000000.

CONFIG_SYS_LBC_MRTPR always has the value 0x20000000.

CONFIG_SYS_LBC_LSDMR_{1,2,4,5} are not set for any mpc83xx board.

CONFIG_SYS_LBC_LSRT is set by one board (to 0x32000000).
