The main idea behind this patch is to avoid redundant board code.
Because of the module similarities of all am335x based phytec boards, we can
merge its code.

So we will have only one "board" in the barebox for phyCORE, phyFLEX.

The most notable problems:
* PCI-enabled barebox just hangs under GXemul;

Instead of introducing new functions each time a new power supply
situation is to be added, this patch adds parameters to mx28_power_init.
Right now there are three parameters:
- has_battery - true when this board has a battery.
- use_battery_input - true when this board is supplied from the
battery input, but has a DC source instead of a real battery
- use_5v_input - true when this board can use the 5V input
The third one is introduced with this patch and allow to boot a board from 5v
(USB) source only. The main necessary change this needs is that the DC-DC
converter must always be sourced from DCDC_4P2 (DROPOUT_CTRL field of
HW_POWER_DCDC4P2)

Since include/linux/linkage.h includes <asm/linkage.h>, the basic
coding style we should follow is:
- <linux/linkage.h> should contain default macro defines
- <asm/linkage.h> can define arch-specific macros and override the
default ones in <linux/linkage.h>
The arch/blackfin/include/asm/linkage.h has redundant defines that
are already defined in <linux/linkage.h>.
Replace it with the one imported from Linux 3.19-rc6.
