[PATCH 5/5] mfd: ab8500-sysctrl: let sysctrl driver work without pdata

[fabio.baltieri@linaro.org (Fabio Baltieri)]

A check for a valid plat->sysctrl was introduced in:

2377e52 mfd: ab8500-sysctrl: Error check clean up

but the driver works just fine even without that initialization data.
This patch removes the check and let the driver go ahead with probe.
