powerpc/qe: add polling timeout to qe_issue_cmd() The qe_issue_cmd() function (Freescale PowerPC QUICC Engine library) polls on a register until a status bit changes, but does not include a timeout to handle the situation if the bit never changes. Change the code to use the new spin_event_timeout() macro, which simplifies polling on a register without a timeout.
