[PATCH 3/3] fpga: mgr: altera-ps-spi: make array dummy static, shrinks object size

[Alan Tull]

From: Colin Ian King <colin.k...@canonical.com>

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)
