Khaja Hussain Shaik Khaji 446a7be36f firmware: qcom_scm: Add a call for getting dload mode 
Add an SCM call to read the dload mode cookie, which can
be used in various drivers to make decisions based on the
dload mode. Earlier, this support was not there and HLOS
was not aware of changes in this cookie, outside of its
domain.
