Remove at91_sys_read() and at91_sys_write() since these are no longer
used. This makes mach/io.h empty so remove that aswell.

Many boards have the same ethernet phy reset function, so share the code
in a common function.
While at it remove the AT91_RSTC offset from the rstc register defines.
AT91_RSTC was the offset between the AT91_SYSTEM_BASE and the reset
controller.

Currently it's hardcoded for each board which defaultenv version is
used. This is unfortunate since some people like the other defaultenv
version better and may want to select it.

This patch removes the board specific environment path
CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via:

	if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC))
		defaultenv_append_directory(defaultenv_<board>);

This way we can make sure that the defaultenv-1 board specific bits are
only compiled in when defaultenv-1 is actually in use.

The next step is to make the defaultenv version selection a user visible
choice.

As the place for the atags now is determined automatically the call
from the boards can be removed.

asm/hardware.h does not have any content except including mach/hardware.h.
include mach/hardware.h directly where needed and get rid of asm/hardware.h

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.

Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

This will allow to drop the config.h and switch to multi board support
