Subject: [PATCH 1/2] at91: sync mach/barebox-arm-head.h

To prepare for multi image support synch the barebox-arm-head.h
header with the arm version.
This include the reservation of a small area for board specific use

at91_udc: add DT support ...

Based on the linux kernel version of the same driver.
Needs to adjust clock names as the clock names used in the device tree
does not match the clocknames used in platform_data.
The clocknames in the device tree are not unique, so it was
not an option to rename the clocks.

It boots and the driver is discovered - no further testing done.

atmel_lcdfb: add DT support ...

Some boards use "have_intensity_bit". To support this the
syntax for lcd_wiring_mode was extended to include this info.
This is an extension compared to the documented bindings,
and an extension the kernel does not support (yet).

The binding documents that there can be more than one gpio to
power on/off the display but current implmentation supports only
one gpio. There are no users that requires more than one gpio
so this is good enough.

The clk name used for hclk differs from device trees and
platform data. We could rename the clocl used in platform data
but the name "hclk" is not unique.

Configure clockname based on configuration method.
Devicetree => hclk
Platform data => hck1

atmel_lcdfb: define power_control gpio in platform_data ...

Simplify board specific code by specifying the power_control
gpio direct in platform data.
Move registration of the GPIO to the driver so we no longer
need to duplicate this for each board.

As an intended side-effect there is no longer
any references to platform_data outside atmel_lcdc_register()
so remove it from struct atmel_lcdfb_info

The implementation assumes that GPIO=0 is the same as no power control.
This prevents us from using any GPIO=0 for power control,
but this is not considered a problem for current users.
Future DT users will not have this limitation.

This commit include a fix so we will actually power
down if requested. Previously this was hardcoded to ON.

fs: Don't bother filesystems without link support with additional stat() calls ...

In __canonicalize_path() we only call stat() to know if the path
is a link or not. When the filesystem doesn't support links we
already know that it's not a link, so we do not need to call stat().
This helps the tftp filesystem since the parent directories of
a file to be opened won't be stat()ed anymore, something tftp
does not support.

fs: avoid pathes with '//' in __canonicalize_path() ...

In __canonicalize_path pathes beginning with '//' can occur. This
is normally not a problem since normalize_path() will clean this
up, but it means we cannot call get_fsdevice_by_path() on these
pathes in this function, as needed in the next patch.
