PPC/PCM030: fix reference clock ...

In order to enable and use USB/OHCI on the MPC5200 the USB PLL register must be
set.

It's not easy to find a correct value for this register, it seems it depends on
the used external reference frequency and some other 'magic' things. There are
some values out in the wild for the 33,333333 MHz and 33,333000 MHz reference
frequency case, but they are not consistent over the boards.

The value used here in this change for the USB PLL register is from the first
days of support for this platform and works at least on the reference
baseboard.

ARM: [phyFLEX,phyCARD]-i.MX6: rename define in flash-headers ...

The files flash-header-*.imxfg contains two defines which are use in
include files flash-header-phytec-*.h. The first define is SETUP_MDCFG0.
In the second define name some RAM size value were used, e.g.
SETUP_S_DL_512MB_1GB or SETUP_1GIB_2GIB_4GIB.

It's better to name also the second define after the register names,
here MMDC1_MDCTL and MMDC1_MDASP, because these values changes for every
RAM configurations and it's consistent with the first define.

The current calculation does not take the 0x10000000 offset where

the current code calculates cs1 start to 0x40000000, but it
has to be 0x10000000 + 0x40000000 = 0x50000000. Add the missing

PBL: console: Make independent of DEBUG_LL ...

With more stuff being done in PBL regular console support gets more and more
useful. This makes the PBL console independent of DEBUG_LL which is only
meant for early debugging but not regular output.
To use the regular PBL console a board must call pbl_set_putc() which stores
a pointer to the putc function to be used.

Devicetree/PPC: fix devicetree's fixup ...

Currently Barebox fails to boot a kernel/devicetree pair on PowerPC.

With of_find_node_by_path() the framework uses a global variable to find
the root node and fails. With of_find_node_by_path_from() and forwarding
the 'root' parameter it works again as expected.

This fixes the following error message at run-time:
