This structure is only used to copy into another structure, so declare
it as const.
This issue was detected using Coccinelle and the following semantic patch:

In the following log you can see a significant difference in the code size
and data segment, hence in the dec segment. This log is the output
of the size command, before and after the code change:
before:
text data bss dec hex filename
15136 5112 0 20248 4f18 drivers/pinctrl/qcom/pinctrl-ssbi-mpp.o
after:
bss dec hex filename
14849 5024 0 19873 4da1 drivers/pinctrl/qcom/pinctrl-ssbi-mpp.o
