arch/unicore32/kernel/clock.c: add readl() and writel() for 'PM_' macros 

Add readl() and writel() for 'PM_' macros, just like another areas have
done within unicored32, or will cause compiling issue.

The related error (allmodconfig for unicored32):

    CC      arch/unicore32/kernel/clock.o
  arch/unicore32/kernel/clock.c: In function 'clk_set_rate':
