clk: mmp: Off by one in mmp_clk_add()
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).
Fixes: 4661fda10f8b ("clk: mmp: add basic support functions for DT support")
