[PATCH] clk: bcm2835: Constify struct debugfs_reg32

[Rikard Falkeborn <rikard.falkeborn@gmail.com>]

bcm2835_debugfs_clock_reg32 is never changed and can therefore be made
const.

This allows the compiler to put it in the text section instead of the
data section.

Before:
   text    data     bss     dec     hex filename
  26598   16088      64   42750    a6fe drivers/clk/bcm/clk-bcm2835.o

After:
   text    data     bss     dec     hex filename
  26662   16024      64   42750    a6fe drivers/clk/bcm/clk-bcm2835.o
