Subject: tools: update test_hmm script to support SP config
Git-commit: e6474b1aeb2a0bb01c925f79cafa829b4b5e05c2
Patch-mainline: v6.0-rc1
References: jsc#PED-1294
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.
