libata: zpodd: make arrays cdb static, reduces object code size
Don't populate the arrays cdb on the stack, instead make them static.
Makes the object code smaller by 230 bytes:
Before:
text data bss dec hex filename
3797 240 0 4037 fc5 drivers/ata/libata-zpodd.o
After:
text data bss dec hex filename
3407 400 0 3807 edf drivers/ata/libata-zpodd.o
