Subject: mmc: dw_mmc: silent verbose log when calling from PM context
From: Shawn Lin <shawn.lin@xxxxxxxxxxxxxx>
commit ce69e2fea093b7fa3991c87849c4955cd47796c9 upstream.
When deploying runtime PM, it's quite verbose to print the
log of ios setting. Also it's useless to print it from system
PM as it should be the same with booting time. We also have
sysfs to get all these information from ios attribute, so let's
skip this print from PM context.
