carl9170 firmware: fixup const volatile register access

Due to heavy usage of all sorts of different optimitations
option, the compiler tries to optimize repeated reads of
const type * away if they are not marked as volatile.
Unfortunately, this breaks the code in several places, as it
causes infinite loops while waiting for hardware to update
BUSY registers.
