sh: share clock framework frequency table code

sh: share clock framework frequency table code

[PATCH 01/04] sh: add pll_clk to sh7785
[PATCH 02/04] sh: add shared clock framework frequency table code [PATCH 03/04] sh: use shared frequency tables on sh7785 [PATCH 04/04] sh: remove clk_ops->build_rate_table()

These patches modify the clkfwk topic branch with the following:
- break out sh7785 pll_clk to remove multiplier from frqmr_recalc()
- implement clk_rate_table_build() and clk_rate_table_round()
- hook in the above functions in the sh7785 code, drop ->build_rate_table()
- remove ->build_rate_table() callback since recalc() can be used instead
