[PATCH 17/22] ARM: at91sam926x use writel rather than pmc accessor function

[Sascha Hauer <s.hauer@pengutronix.de>]

The pmc accessor function depends on a compile time base address, so
rather use writel directly. In this case we can hardcode the base
address again since all at91sam926x SoCs have the same pmc base address.
