Currently arch specific headers can be included with
longer possible as there won't be a single mach anymore.
Move all socfpga specific header files to include/mach/socfpga/ to
prepare for multi-arch support.

Setting BIT(1) in the ARRIA10_SYSMGR_NOC_ADDR_REMAP_VALUE results in
mapping the OCRAM to 0x0, at least for the CPU. Peripherals doing
DMA like the SDMMC controller see the SDRAM instead. Linux happens
to use this low memory for DMA sometimes and things explode nicely
at that point.
Clear the OCRAM mapping so that both the CPU and DMA controllers access
SDRAM.

Move the setup of the shared- and fpgapins to its own function.
These pins can only be configured and let out of reset after the FPGA has been
programmed.

Instead of copy+pasting the debug_ll messages to every new board,
move them to the respective functions.

Arria10 is a SoC + FPGA like the Cyclone5 SoCFPGA that
is already supported in barebox.
Both a the same in some parts, but totaly different in
others. Most of the hardware blocks are the same in the
SoC parts. The OCRAM is larger on the Arria10 and the
SDRAM controller is different.
The serial core only supports 32bit accesses (different to
the 8bit accesses on the Cyclone5).
As Arria10 has 256KB of OCRAM, it is possible to fit a larger
barebox (and/or use PBL) instead of the two stage bootprocess
used on the Cyclone5 and its 64KB OCRAM.
