[PATCH] ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688

> The Kconfig-Option OMAP4_ERRATA_I688 is never visible due to a
> contradiction in it's dependencies.
> The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an
> enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be
> enabled. These options inherit a dependency from an enclosing menu,
> that requires ARCH_MULTIPLATFORM to be 'enabled'.
> This is a contradiction and made this option also unavailable for
> non-multiplatform configurations.
> 
> Since there are no selects on OMAP4_ERRATA_I688, which would ignore
> dependencies, the code related to that option is dead and can be
> removed.

> This (logical) defect has been found with the undertaker tool.

Seems to boot fine, so applying into omap-for-v4.1/fixes-not-urgent.
