alucard_governor: added cpufreq_relation parameter for max possible frequency during scaling.............
alucard cpu govenor: added cpus_up_rate, cpus_down_rate. They are useful for normalizing cpu frequency scaling with cpus load.
wcd9xxx: core: Fix crash while headset insert and remove

When insert and remove headset continuously observe crash.
In the interrupt table for wcd9306, there is a interrupt
number of WCD9XXX_IRQ_RESERVED_2 (value 32).
In IRQ driver, irqs will be dispatched  based on this
interrupt table. But for WCD9XXX_IRQ_RESERVED_2, this
value being 32 and BIT_BYTE will be 4 whereas number
of interrupt registers are 0 to 3 only.
Here status array used to check interrupt set, access each
entry of interrupt table and see if bit mask is set.
so, when checking for WCD9XXX_IRQ_RESERVED_2 it will
access out of bound array status[4] which will return
unexpected value.
In failed case, status[4] matches bitmask for 32nd bit
and dispatches irq for invalid entry causing crash.
Remove the entry as it is not a valid entry and causing
out of bound access for wcd9306 and wcd9320.
