Add support for printing from which device the SoCFPGA board booted.
This decodes the BSEL settings and prints it in human readable form.

Write necessary magic value into the Warm Boot from ON-Chip RAM
group Enable register to enable Warm reset support. Instead of
doing this in the reset_cpu() function, we do it in arch early
init to avoid breaking old kernel code which expects this magic
value to be already written into this register.
This magic is originally excavated from common/spl/spl.c in the
u-boot port from altera, where this value was written just before
the SPL jumped to actual U-Boot in the RAM.

Replace all those ad-hoc reset functions, which were all copies
of the same invocation of clrbits_le32() anyway, with one single
unified function, socfpga_per_reset(), with necessary parameters.

Our recent trend is to collect SoC files into arch/arm/mach-(SOC).
