clk: mmp: Off by one in mmp_clk_add()

[ Upstream commit 2e85c57493e391b93445c1e0d530b36b95becc64 ]

The > comparison should be >= or we write one element beyond the end of
the unit->clk_table[] array.

(The unit->clk_table[] array is allocated in the mmp_clk_init() function
and it has unit->nr_clks elements).
