Bluetooth: btintel: make array 'param' static, shrinks object size
Don't populate the const read-only array 'param' on the stack but instead
make it static. Makes the object code smaller by nearly 20 bytes:
Before:
text data bss dec hex filename
11605 2629 64 14298 37da linux/drivers/bluetooth/btintel.o
After:
text data bss dec hex filename
11531 2685 64 14280 37c8 linux/drivers/bluetooth/btintel.o
(gcc version 7.2.0 x86_64)
