Summary
soc: fsl: qbman: Use raw spinlock for cgr_lock
Details

In the Linux kernel, the following vulnerability has been resolved:

soc: fsl: qbman: Use raw spinlock for cgr_lock

smpcallfunction always runs its callback in hard IRQ context, even on PREEMPTRT, where spinlocks can sleep. So we need to use a raw spinlock for cgrlock to ensure we aren't waiting on a sleeping task.

Although this bug has existed for a while, it was not apparent until commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change") which invokes smpcallfunctionsingle via qmanupdatecgrsafe every time a link goes up or down.
