Subject: [PATCH] ARM: OMAP: remove some dead code

A check for CONFIG_CBUS_TAHVO_USB was added in v2.6.17. The related
Kconfig symbol has never been part of the tree. Remove that check.

Replace the while (...) loop with a simple if (...) statement, while
we're at it.

Untested, as usual.

A quick search across the history of the tree suggests CBUS_TAHVO_USB
was N770 related. Not that this matters much.
