clk: moxart: remove unnecessary statics

Remove unnecessary static on local variable _base_ in both functions
moxart_of_pll_clk_init() and moxart_of_apb_clk_init(). Such variables
are initialized before being used, on every execution path throughout
the mentioned functions. The statics have no benefit and, removing
them reduce 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. Also,
notice that the bss segment is reduced down to zero. This log is the
output of the size command, before and after the code change:
