arm: socfpga: Move wrappers into platform directory

Move the wrappers for QTS-generated files into platform directory
out of the board directory. The trick here is to add -I to CFLAGS
such that it points to the board directory in source tree and thus
the qts/ directory there is still reachable.

+ * Yes, dear reader, we're including a C file here, this is no mistake.
+ * But this time around, we do even more perverse hacking here to be
+ * compatible with QTS headers and obtain reasonably nice results too.
+ *
+ * First, we define _PRELOADER_PINMUX_CONFIG_H_, which will neutralise
+ * the pinmux_config.h inclusion in pinmux_config.c . Since we are
+ * probing everything from DT, we do NOT want those macros from the
+ * pinmux_config.h to ooze into our build system, anywhere, ever. So
+ * we nip it at the bud.
+ *
+ * Next, pinmux_config.c needs CONFIG_HPS_PINMUX_NUM and uses it to
+ * specify sized array explicitly. Instead, we want to use ARRAY_SIZE
+ * to figure out the size of the array, so define this macro as an
+ * empty one, so that the preprocessor optimizes things such that the
+ * arrays are not sized by default.
