Don't populate the const read-only array 'req' on the stack but instead
make it static. Makes the object code smaller by over 40 bytes:
Before:
text data bss dec hex filename
8497 3408 128 12033 2f01 linux/drivers/bluetooth/bpa10x.o
After:
text data bss dec hex filename
8366 3496 128 11990 2ed6 linux/drivers/bluetooth/bpa10x.o
(gcc version 7.2.0 x86_64)
