In order to configure device generic in test_hmm, two
module parameters should be passed, which correspon to the
SP start address of each device (2) spm_addr_dev0 &
spm_addr_dev1. If no parameters are passed, private device
type is configured.
v5:
Remove devmem->pagemap.type = MEMORY_DEVICE_PRIVAT
new ioctl cmd added to query zone device type. This will be
used once the test_hmm adds zone device generic type.

2. dec thread gets the chance to finish begin_use

Since activating power management while submitting work is problematic
cancel_delayed_work() must have been called during begin use or otherwise we

It caused historical lifetime issues and corner cases.
