[patch 2.6.19-git] fix more workqueue build breakage (tps65010)

[David Brownell <david-b@pacbell.net>]

More fixes to build breakage from the work_struct changes ... this
updates the tps65010 driver.  Plus, fix some dependencies related
to the way it's used on the OMAP OSK:  force static linking there,
since the resulting kernel can't link.

NOTE that until the i2c core gets fixed to work without SMBUS_QUICK,
kernels needing this driver must still use "tps65010.force=0,0x48"
on the command line.
