Subject: drm/panfrost: Reduce the amount of logs on deferred probe
Git-commit: e63adeccc0bbba34a7b988b8898bebbd5bbb6461
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
There is no point to print deferred probe (and its failures to get
resources) as an error. Also there is no need to print regulator errors
twice.
In case of multiple probe tries this would pollute the dmesg.
