Philippe Reynes d28c5920cd include: linux: io: define devm_ioremap on board with ioremap
The macro devm_ioremap is only defined for configuration
that doesn't have ioremap. But this macro may also be
defined on configuration with ioremap.
This patch remove the condition for the macro devm_ioremap,
so it's always defined.
