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

This patch makes the AT91 clock.c support processor-generic (AT91RM9200
and AT91SAM9xxx).  The clocks supported by a particular AT91 processor
are defined in the processor-specific file and are registered with
clock.c at startup.

This is more preparation for adding support for the new Atmel AT91SAM9
processors.

Changes include:
- Replace AT91_BASE_* with AT91RM9200_BASE_*
- Replace AT91_ID_* with AT91RM9200_ID_*
- ROM, SRAM and UHP address definitions moved to at91rm9200.h.
- The raw AT91_P[ABCD]_* definitions are now depreciated in favour of
the GPIO API.

Patch from Andrew Victor

Some updates to the clock infrastructure for the AT91RM9200.

1. Hard-coded values replaced with names defined in at91rm9200_sys.h.
2. Added the four PIO clocks, which are enabled at startup.
3. At startup, disable all unused clocks.
4. Minor bugfix for usage counts associated with MCK. [Patch from David
Brownell]
5. Added at91_clock_associate() function to associate device & function
with a particular clock.  [Patch from David Brownell]

Patch from Andrew Victor

This patch includes a few changes to the clock support on the
AT91RM9200.

1. Added definitions for Ethernet, MMC, TWI, USARTs, and SPI peripheral
clocks.

2. Replaced some hard-coded hex values with the text definitions in
at91rm9200_sys.h.

3. If the USB96M bit is set for PLLB, then the rate of PLLB is not
affected but only the USB Host/Device clocks which are derived from it.

Patch from SAN People

Following changes were made to clock.c:

1) Replaced <asm/hardware/clock.h> with <linux/clk.h>
2) Removed old unused clk_enable & clk_disable.
3) Replaced clk_use/clk_unuse with clk_enable/clk_disable.

Otherwise it's the same as the previous patch.
