[PATCH] drivers:cpufreq:unicore32: fix typo issue for 'clk'

[Chen Gang <gang.chen.5i5j@gmail.com>]

Need use 'clk' instead of 'mclk', which is the original removed local
variable.

The related original commit:

  "652ed95 cpufreq: introduce cpufreq_generic_get() routine"

The related error with allmodconfig for unicore32:

    CC      drivers/cpufreq/unicore2-cpufreq.o
