This structure is only used to copy into other 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
18958 9000 128 28086 6db6 drivers/pinctrl/bcm/pinctrl-bcm2835.o
after:
text data bss dec hex filename
18764 8912 128 27804 6c9c drivers/pinctrl/bcm/pinctrl-bcm2835.o
