devfs & mtd: add MEMERASE ioctl support ...

To make that, we need to shift mtd_erase before mtd_ioctl.
ubi-utils need that, especially ubiformat.

esdctl: fix reset default bug on i.MX27/31 ...

The i.MX27/31 have the second chip select enabled by reset default.
This can be considered as a hardware bug, because even boards which

initialization sequence. Detect this reset default setting and disable
this chipselect then to be able to properly detect the SDRAM size.

drivers/base: fix corrupt device tree ...

dev_add_child is a very unsafe function. If called multiple times
it allows setting the same device to different parents thus corrupting
the siblings list. This happens regularly since:

|    bus: add bus device

|    automatically add it as parent of any bus device if none already specified
|

This patch fixes this by adding a device to its parents children list in
register_device so that dev_add_child is no longer needed. This function
is removed from the tree. Now callers of register_device have to clearly
set the parent *before* registering a device.

net phylib: Call phy_update_status when no link is present ...

We call phy_update_status only once in 5 seconds. This makes
sure we do not have great overhead when using ethernet devices.
However, if phylib tells us the link is down anyway, there won't
be ethernet transfers, so it doesn't hurt to call phy_update_status
in this case. This makes sure we can use the ethernet device when
the link comes up and do not have an additional 5 second penalty
in this case.
