clk: tegra: common periph_clk_enb_refcnt and clks
This patch makes periph_clk_enb_refcnt a global array, dynamically allocated at boottime. It simplifies the macros somewhat and allows clocks common to several Tegra SoCs to be defined in a separate files. Also the clks array becomes global and dynamically allocated which allows the DT registration to be moved to a generic funcion. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
