Neil Armstrong 4aedcd4aa6 mfd: rk8xx: fixup devices registration with PLATFORM_DEVID_AUTO 
Since commit 210f418f8a ("mfd: rk8xx: Add rk806 support"), devices are
registered with "0" as id, causing devices to not have an automatic device id
and prevents having multiple RK8xx PMICs on the same system.

Properly pass PLATFORM_DEVID_AUTO to devm_mfd_add_devices() and since
it will ignore the cells .id with this special value, also cleanup
by removing all now ignored cells .id values.

Now we have the same behaviour as before rk806 introduction and rk806
retains the intended behavior.

This fixes a regression while booting the Odroid Go Ultra on v6.6.1:
sysfs: cannot create duplicate filename '/bus/platform/devices/rk808-clkout'
