some drivers switch away from OMAP-specific GPIO calls
This updates most of the OMAP drivers which are in mainline to
switch to using the cross-platform GPIO calls instead of the
older OMAP-specific ones.
This is all fairly brainless/obvious stuff. Probably the
most interesting bit is to observe that the omap-keypad

non-OMAP matrix keypads. (That would improve with hardware
IRQ debouncing enabled, of course...)

- declare and use platform_data structure for that core
- stop hard-wiring the irq numbers
- check functionality that's really used: I2C, not SMBus
Cleanup:
- remove needless "client string"
- remove some fake "bool" types
- include catalog part numbers (TPS659{5,3,2}0)
- diagnostics should identify the driver!
To use this, all boards with these chips will need to declare this chip

sctp: do not enable peer features if we can't do them.
Do not enable peer features like addip and auth, if they
are administratively disabled localy. If the peer resports
that he supports something that we don't, neither end can
use it so enabling it is pointless. This solves a problem
when talking to a peer that has auth and addip enabled while
we do not. Found by Andrei Pelinescu-Onciul <andrei@iptel.org>.

[ARM] 5255/1: Update jornada ssp to remove build errors/warnings
* Adds ssp functions into header so we don't get
"implicit declaration" error at builtime.
* Converts jornada_ssp_start/end functions into voids with
proper declarations (to avoid "prototype..." warning).
* Sorts include files in alphabetical order
* Minor comment changes

sctp: set the skb->ip_summed correctly when sending over loopback.
Loopback used to clobber the ip_summed filed which sctp then used
to figure out if it needed to do checksumming or not. Now that
loopback doesn't do that any more, sctp needs to set the ip_summed
field correctly.
