Subject: [PATCH v3 13/32] clk: at91: sama7d65: switch to parent_hw and parent_data

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

Switch the system clocks to use parent_hw and parent_data. Having this
allows the driver to conform to the new clk-system API.

The parent registration is after the USBCK registration due to one of
the system clocks being dependent on USBCK.
