zynq: treat ps7_init.c/h as external files to ignore them
ps7_init.c and ps7_init.h are supposed to be exported by hw project
and copied to board/xilinx/zynq/ directory.
We want them to be ignored by git.
So what we should do is to always treat them as external files
rather than replacing ps7_init.c
This commit does:
- Move a weak function ps7_init() to arch/arm/cpu/armv7/zynq/spl.c
and delete board/xilinx/zynq/ps7_init.c
- Compile board/xilinx/zynq/ps7_init.c only when it exists
- Add .gitignore to ignore ps7_init.c/h
