38884dabbe remove irq support fragments 
We never had interrupt support in barebox and we have no plans to
add interrupt support. Even if we do I doubt the current fragments
of irq support are helpful, so remove them.

1c9c937a6a ppc mpc5200b: cleanup lowlevel startup 
The old startup process consisted of several CFG_LOWBOOT,
CFG_RAMBOOT ifdeffery which I do not understand. So remove
all this and replace it with:

- put the entry point for second stage loaders to offset 0x0
  so that we can do a go /dev/ram0 to start a second barebox
- When we come from the reset vector assume MBAR is at 0x80000000
- When we come from the second stage entry assume that
  SPR 311 is in sync with the current MBAR address.
- Switch MBAR to 0xf0000000 and we are done.

d092fe6999 Remove PPC support for IDE. 
Based on a suggestion from S. Hauer, we don't currently need any IDE
support, but we can always add it back later if we choose.  There
don't appear to be any other IDE-related source files in the tree.

It needs some manual fixup following in the next patch
