Warnings being suppressed, we can now turn on -Werror for boards which did
not have it already (devboards and xss1500).

Register the PCMCIA driver on all boards supported by it,
get rid of now-unused pcmcia macros in the board headers
(and subsequently empty pb1100/pb1500 ones).

All Alchemy development boards have external CPLDs with a few registers
in them. They all share an identical register layout with only a few
minor differences (except the PB1000) in bit functions and base
addresses.
This patch
- adds a primitive facility to initialize and use these external
registers,
- replaces all occurrences of bcsr->xxx accesses with calls to the new
functions (the pb1200 cascade irq handling code is special).
- collects BCSR register information scattered throughout the board
headers in a central place.

Replace the current sysctl-based suspend interface with a new sysfs-
based one which also uses the Linux-2.6 suspend model.
To configure wakeup sources, a subtree for the demoboards is created
under /sys/power/db1x:
sys/
`-- power
`-- db1x
|-- gpio0
|-- gpio1
|-- gpio2
|-- gpio3
|-- gpio4
|-- gpio5
|-- gpio6
|-- gpio7
|-- timer
|-- timer_timeout
|-- wakemsk
`-- wakesrc
The nodes 'gpio[0-7]' and 'timer' configure the GPIO0..7 and M2
bits of the SYS_WAKEMSK (wakeup source enable) register. Writing '1'
enables a wakesource, 0 disables it.
The 'timer_timeout' node holds the timeout in seconds after which the
TOYMATCH2 event should wake the system.
The 'wakesrc' node holds the SYS_WAKESRC register after wakeup (in hex),
the 'wakemsk' node can be used to get/set the wakeup mask directly.
For example, to have the timer wake the system after 10 seconds of sleep,
the following must be done in userspace:
echo 10 > /sys/power/db1x/timer_timeout
echo 1 > /sys/power/db1x/timer
echo mem > /sys/power/sleep
This patch also removes the homebrew CPU frequency switching code. I don't
understand how it could have ever worked reliably; it does not communicate
the clock changes to peripheral devices other than uarts.
