Add IRQ_AFFINITY_MANAGED flag and related kernel APIs so that
kernel driver can modify an irq's status in such a way that
user space affinity change will be ignored. Kernel space's
affinity setting will not be changed.

Interupts marked with this flag are excluded from user space interrupt
affinity changes. Contrary to the IRQ_NO_BALANCING flag, the kernel internal
affinity mechanism is not blocked.
This flag will be used for multi-queue device interrupts.

Cluster capacities should reflect differences in efficiency of
different clusters even in the absence of cpufreq. Currently
capacity is updated only when cpufreq policy notifier is received.
Therefore placement is suboptimal when cpufreq is turned off. Fix
this by updating capacities and load scaling factors during cluster
detection.

Bus clocks are managed via bus apis and hence move to using them for
enabling bus clocks. The previous method could enable a bus clock at a
higher than required frequency, wasting power.
The power on sequence is regulator on, bus vote, and then enable
remaining clocks.
Remove all clocks which are of RPM_SMD type (including mmssnoc_axi_clk)
since these are managed by the bus driver. Using an active-only bus vote
instead should save power when APPS is power collapsed.
Keep the mmss_mnoc_ahb_clk because it is a branch clock type which is
not managed by the bus driver. No active-only mode is available for this
clock.

A misplaced return statement causes an early return from disabling OTG.
If OTG is enabled when a source is attached then Type-C detection will
fail. Therefore, OTG should never be blocked from being disabled.
Remove all of the early returns that could potentially block the
register write which disables OTG.

If the rate of the clock being measured changes at the same
time clock_debug_measure_get() is called, there can be a
miscalculation of the value of the divider between the
measurement circuitry and clock output. Acquiring the prepare
lock fixes the race since it prevents clock rate changes during
measurement.
