Subject: [PATCH v3 02/15] ARM: socfpga: introduce common ARCH_INTEL_SOCFPGA

Simplify 32-bit and 64-bit Intel SoCFPGA Kconfig options by having only
one for both of them.  This the common practice for other platforms.
Additionally, the ARCH_SOCFPGA is too generic as SoCFPGA designs come
from multiple vendors.
