fpga: mgr: altera-ps-spi: make array dummy static, shrinks object size
Don't populate the const array dummy on the stack but instead
make it static. Makes the object code smaller by 26 bytes:
Before:
text data bss dec hex filename
7371 2032 0 9403 24bb drivers/fpga/altera-ps-spi.o
After:
text data bss dec hex filename
7281 2096 0 9377 24a1 drivers/fpga/altera-ps-spi.o
(gcc version 8.2.0 x86_64)
