Commit ff6d365898 ("soc: qcom: qmi: use const for struct
qmi_elem_info") allows QMI message encoding/decoding rules to be
const, so do that for QCOM PDR.

Sparse reports this repesentative issue
pdr_internal.h:31:22: warning: symbol 'servreg_location_entry_ei' was not declared. Should it be static?
Similar for other servreg_*
Global variables should not be defined in header files.
This only works because pdr_internal.h is only included
by pdr_interface.c. Single file use variables should be
static so add static to their storage-class specifiers.

The array type of get_domain_list_resp is incorrectly marked as NO_ARRAY.
Due to which the following error was observed when using pdr helpers with
the downstream proprietary pd-mapper. Fix this up by marking it as
VAR_LEN_ARRAY instead.

Qualcomm SoCs (starting with MSM8998) allow for multiple protection domains
to run on the same Q6 sub-system. This allows for services like ATH10K WLAN
FW to have their own separate address space and crash/recover without
disrupting the modem and other PDs running on the same sub-system. The PDR
helpers introduces an abstraction that allows for tracking/controlling the
life cycle of protection domains running on various Q6 sub-systems.
