[PATCH -resend v2] clk: pistachio: Fix initconst confusion

[Jiri Slaby]

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

A variable pointing to const isn't const itself. It has to contain
"const" keyword after "*" too. So to keep it in __initconst (and not
mark properly as __initdata), add the "const" keyword exactly there.

Note we need to update struct pistachio_mux too. On the other hand, the
clk core already counts with "const char *const" already.

[js] more explanatory commit message.

Notes:
    [v2] as suggested by Stephen, instead of switching to __initdata, make
         it real const
