Subject: [PATCH v3 2/4] clk: at91: sama7d65: Add missing clk_hw to parent_data

From: Ryan Wanner <Ryan.Wanner@...rochip.com>

The main_xtal clk_hw struct is not passed into parent_data.hw causing
the main_osc to not have a parent causing a corrupted clock tree.
Passing the main_xtal struct into the parent_data struct will
ensure the correct parent structure for main_osc and a correct clock
tree.
