MLK-13457 ARM: imx: busfreq: fix deadlock detected by lockdep

The deadlock scenario is the following:

1. We schedule low_bus_freq_handle() but it does not run yet.

2. We run set_high_bus_freq() or some other function, that does the
following two things: (a) takes the busfreq mutex and (b)
synchronously cancel the low_bus_freq_handle work

If between (a) and (b) the low_bus_freq_handle work starts running, it
will take the bus freq mutex and block which will cause (b) to
deadlock since the work will never finish now.

To fix this issue avoid synchronously canceling the work and instead
use a new global variable (protected by the busfreq mutex) to mark the
cancellation and abort the work when it is scheduled. In order to
avoid unnecessary schedules we also try to cancel the work with
cancel_delayed_work().
