[PATCH] clk: moxart: remove unnecessary static in moxart_of_pll_clk_init()

[Gustavo A. R. Silva]

Remove unnecessary static on local variable _base_.
Such variable is initialized before being used,
on every execution path throughout the function.
The static has no benefit and, removing it reduces
the code size.

This issue was detected using Coccinelle and the following semantic patch:

@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;

In the following log you can see the difference in the code size and,
a significant difference in bss segment. This log is the output
of the size command, before and after the code change:

before:
   text    data     bss     dec     hex filename
   1724     384     128    2236     8bc drivers/clk/clk-moxart.o

after:
   text    data     bss     dec     hex filename
   1713     328      64    2105     839 drivers/clk/clk-moxart.o
