power: supply: axp20x_usb_power: Drop unnecessary static

Drop static on a local variable, when the variable is either first
initialized or never used, on every possible execution path through the
function.  The static has no benefit, and dropping it reduces the code
size.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;
// </smpl>

The change in code size is indicates by the following output from the size
command.

before:
   text    data     bss     dec     hex filename
   2865     252       8    3125     c35 drivers/power/supply/axp20x_usb_power.o

after:
