The global mutex of 'gdp_mutex' is used to serialize creating/querying
glue dir and its cleanup. Turns out it isn't a perfect way because
part(kobj_kset_leave()) of the actual cleanup action() is done inside
the release handler of the glue dir kobject. That means gdp_mutex has
to be held before releasing the last reference count of the glue dir
kobject.
This patch moves glue dir's cleanup after kobject_del() in device_del()
for avoiding the race.

If "core" memory resource is not specified, the driver could end up
dereferencing a null pointer.
Fix this by returning -EINVAL when core resource is missing.

When camera is stopped the current reset sequence was causing
bus error on next start. Avoid the bus error by following
the reset sequence of overflow recovery and reset the registers
as well on stop.

Device bootloader enters deep sleep and turns off
its clock after 1 second of inactivity.
Waking up from this stage takes several milliseconds
and can cause PCIe timeout.
To prevent that, we need to add HALP vote in the reset
flow which will prevent the BL from turning off its
XTAL.
