core_ctl is needed for SDM660 but not for SDM630. Both targets
share the same defconfig. So it can not be compiled out. Use
core_ctl_disable_cpumask kernel parameter to disable core_ctl
for SDM630.

core_ctl can be completely disabled from a kernel parameter now.
Add a check to bail out early from the boost API.

Add a kernel parameter called "core_ctl_disable_cpumask" to
specify the CPUs for which core_ctl is not needed. As
core_ctl operates on a cluster basis, all of the CPUs in a
given cluster must be specified to disable core_ctl on that
cluster.

In the cases that have FPC cable between main board and sub-board, USB
connector located on sub-board, add re-drive chipset on sub-board to
make sure the signal of rx/tx for super-speed is good enough.

There is a leakage path in the TADC block while the device is shutdown
or is in deep sleep mode. To fix this hw problem, the driver needs to
disable hw conversions and enable direct test mode while charger is
plugged out, kernel goes to suspend or device shuts down. The driver
needs to undo those changes when charger is plugged in, kernel resumes
or device powers up.
Moreover while disabling hw conversions it is advisable to wait until
the current conversion is complete.
To realize this
* create a tadc_disable_votable, where the three usecases viz. charger
presence, suspend/resume and shutdown will vote. Enabling it will
disable hw conversions and enable direct test mode and vice versa for
disabling case.
* update complete to complete all since the disable path may be waiting
for conversion to complete.
* create a power supply notifier hook to get the usb presence/absence
notifications.
* add suspend,resume and shutdown driver callbacks that vote for
enabling/disabling tadc.
* prevent more requests coming in when the tadc is disabled.
* skip printing an error reading a channel for requests coming after
tadc is disabled. Return -ENODATA error for these situations.
* since we are introducing a secure write well beyond 0x3652, update the
code to treat everything beyond 0x3652 as locked.
