mmc: mediatek: Remove redundant runtime PM calls
Commit 9250aea76bfc ("mmc: core: Enable runtime PM management of host devices"), made some calls to the runtime PM API from the driver redundant. Especially those which deals with runtime PM reference counting, so let's remove them. Cc: Chaotian Jing <chaotian.jing@mediatek.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
