[PATCH] AVR32: Use __raw MMIO access for internal peripherals
The read[bwl] and write[bwl] functions are meant for accessing PCI
devices. How this is achieved on AVR32 is unknown, as there are no
systems with a PCI bridge available yet.
On-chip peripheral access, however, should not depend on how we end
up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl]
is the right thing to do for on-chip peripherals. This patch converts
the drivers for the static memory controller, interrupt controller,
PIO controller and system manager to use __raw MMIO access.
