Add two more parameters to set spm_addr_dev0 & spm_addr_dev1
addresses. These two parameters configure the start SP
addresses for each device in test_hmm driver.
Consequently, this configures zone device type as coherent.

v2:
Add more mknods for device coherent type. These are represented under
/dev/hmm_mirror2 and /dev/hmm_mirror3, only in case they have created
at probing the hmm-test driver.
