[ARM] 3954/1: AT91: Update drivers for new headers

This patch updates the drivers (and other files) which include the
hardware headers.  This fixes the breakage introduced in patches 3950/1
and 3951/1 (those patches were getting big).

The AVR32 architecture uses the same serial driver and had its own copy
of at91rm9200_pdc.h.  Renamed it to at91_pdc.h
