clk: clk-divider: add clk_register_divider_table()
The existing clk_register_divider() only supports linear or
power-of-two divider mappings. Some hardware (e.g. i.MX6 PLL5
post_div and video_div) uses non-linear register-value-to-divisor
mappings that require a lookup table.
Add clk_register_divider_table() which accepts a clk_div_table,
and reimplement clk_register_divider() as a wrapper passing
table=NULL.
