Although of_platform_device's can have a shutdown routine, at the moment
the bus code doesn't actually call it. So add the required glue to

Iterating through a device node's parents is simple enough, but dealing
with the refcounts properly is a little ugly, and replicating that logic
is asking for someone to get it wrong or forget it all together, eg:

while (dn != NULL) {
	/* loop body */
	tmp = of_get_parent(dn);
	of_node_put(dn);
	dn = tmp;
}

So add of_get_next_parent(), inspired by of_get_next_child().  The
contract is that it returns the parent and drops the reference on the
current node, this makes the loop look like:

while (dn != NULL) {
	/* loop body */
	dn = of_get_next_parent(dn);
}

This patch converts cpmac to the new Fixed PHY infrastructure, though it
doesn't fix all the problems with that driver. I didn't even bother to
test this patch to compile, because cpmac driver is broken in several ways:

1. This driver won't compile by itself because lack of its header describing
   platform data;
2. It assumes that fixed PHYs should be created by the ethernet driver.
   It is wrong assumption: fixed PHYs creation is platform code authority,
   driver must blindly accept bus_id and phy_id platform data variables
   instead.

Also, it seem that that driver doesn't have actual in-tree users, so
nothing to fix further.

The main purpose of that patch is to get rid of the following Kconfig
warning:

scripts/kconfig/conf -s arch/powerpc/Kconfig
drivers/net/Kconfig:1713:warning: 'select' used by config symbol
'CPMAC' refers to undefined symbol 'FIXED_MII_100_FDX'

Teach the debug logging macro to differentiate between log levels based on the
type of debug level enabled specifically instead of a threshold-based one.
Thus, convert tape->debug_level to a bitmask that is written to over /proc.

Also,
- cleanup and simplify the debug macro thus removing a lot of code lines,
- get rid of unused debug levels,
- adjust the loglevel at several places where it was simply missing (e.g.
  idetape_chrdev_open())
- move the tape ptr initialization up in idetape_chrdev_open() so that we can
  use it in the debug_log macro earlier in the function.

The commit 139ddfca ("ide: move handling of
I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe
check vs ide_hwif_request_regions() call (so that we now reserve I/O regions
before checking for hwif->noprobe).  However ide-generic host driver depended
on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots.

Fix it by passing only indexes of non-empty slots to ide_device_add_all()
from ide_generic_init().
