[PATCH] clk: pistachio: Use flexible array for clock table

[PATCH] clk: pistachio: Use flexible array for clock table

[Rosen Penev]

Store the clock lookup table in the Pistachio clock provider
allocation instead of allocating it separately.

This ties the table lifetime directly to the provider and removes a
separate allocation failure path while preserving the clk_onecell_data
lookup interface.
