powerpc: Fix cpufreq drivers after cpufreq core changes
This updates the cpufreq drivers in arch/powerpc so they build again
after the core cpufreq changes that broke them in commit

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:
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.

cxgb3: Keep LRO off if disabled when interface is down
I have a system with a Chelsio adapter (driven by cxgb3) whose ports are
part of a Linux bridge. Recently I updated the kernel and discovered
that things stopped working because cxgb3 was doing LRO on packets that
were passed into the bridge code for forwarding. (Incidentally, this
problem manifested itself in a strange way that made debugging a bit
interesting -- for some reason, the skb_warn_if_lro() check in bridge
didn't trigger and these LROed packets were forwarded out a forcedeth
interface, and caused the forcedeth transmit path to get stuck)
This is because cxgb3 has no way of keeping state for the LRO flag until
the interface is brought up, so if the bridging code disables LRO while
the interface is down, then cxgb3_up() will just reenable LRO, and on my
Debian system at least, the init scripts add interfaces to a bridge
before bringing the interfaces up.
Fix this by keeping track of each interface's LRO state in cxgb3 so that
when bridge disables LRO, it stays disabled in cxgb3_up() when the
interface is brought up. I did this by changing the rx_csum_offload
flag into a pair of bit flags; the effect of this on the rx_eth() fast
path is miniscule enough that it should be fine (eg on x86, a cmpb
instruction becomes a testb instruction).
