Gustavo A. R. Silva 75db1ba159 pinctrl: qcom: ssbi-gpio: constify gpio_chip structure
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:

@r disable optional_qualifier@
identifier i;
position p;
@@
static struct gpio_chip i@p = { ... };

@ok@
identifier r.i;
expression e;
position p;
@@
e = i@p;

@bad@
position p != {r.p,ok.p};
identifier r.i;
struct gpio_chip e;
@@
e@i@p

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
 struct gpio_chip i = { ... };

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
  17061    6992       0   24053    5df5 drivers/pinctrl/qcom/pinctrl-ssbi-gpio.o

after:
   text    data     bss     dec     hex filename
  16777    6904       0   23681    5c81 drivers/pinctrl/qcom/pinctrl-ssbi-gpio.o
