Whenever work is enqueued for a remote CPU, smp_call_function_many_cond()
may need to wait for that work to be completed. However, if no work is
enqueued for a remote CPU, because the condition func() evaluated to false
for all CPUs, there is no need to wait.
Set run_remote only if work was enqueued on remote CPUs.
Document the difference between "work enqueued", and "CPU needs to be
woken up"

sys_futex_wait() expects a struct __kernel_timespec pointer for the
timeout, but the provided struct timespec pointer is of type struct
old_timespec32 when compiled for 32-bit architectures, unless they use
64-bit timespecs already.
Make it work for all variants by converting the provided timespec value
into a local struct __kernel_timespec and provide a pointer to it to the
syscall. This is a pointless operation for 64-bit, but this is not a
hotpath operation, so keep it simple.
This fix is based off [1]

There are a few differences in the power on/off functions between PCIE
and USB. The changes in the power off function in particular are needed
for the RTL8832BU to be able to power on again after it's powered off.
While the RTL8832BU appears to work without the changes in the power on
function, it's probably best to implement them, in case they are needed
in some situations.
