Patch from Lennert Buytenhek

This patch adds support for the Cirrus ep93xx series of CPUs.  The
ep93xx is an ARM920T based CPU with two VICs, PL010 based UARTs,
IrDA, MaverickCrunch floating point coprocessor, between 24 and 64
GPIOs, ethernet, OHCI USB and, depending on the model, pcmcia, raster
engine, graphics accelerator, IDE controller and a bunch of other
stuff.

This patch adds the core ep93xx support code, and support for the
Glomation GESBC-9312-sx and the Technologic Systems TS-72xx SBCs.

+ * 3 (32 bit) count down at 508 kHz, are self-reloading, and can generate
+ * an interrupt on underflow.  Timer 4 (40 bit) counts down at 983.04 kHz,
+ * is free-running, and can't generate interrupts.
+ *
+ * The 508 kHz timers are ideal for use for the timer interrupt, as the
+ * most common values of HZ divide 508 kHz nicely.  We pick one of the 16
+ * bit timers (timer 1) since we don't need more than 16 bits of reload
+ * value as long as HZ >= 8.
+ *
+ * The higher clock rate of timer 4 makes it a better choice than the
+ * other timers for use in gettimeoffset(), while the fact that it can't
+ * generate interrupts means we don't have to worry about not being able
+ * to use this timer for something else.  We also use timer 4 for keeping
