mfd: rtsx: Add shutdown callback in rtsx_pci_driver
Some actions to clear power state should be handled in .shutdown callback in rtsx_pci_driver. This patch adopts the following measures to catch this goal: 1. Add a function rtsx_pci_power_off to abstract the common ops in .shutdown and .suspend 2. Add pcr->ops->force_power_down to fulfill the individual action for each reader model Signed-off-by: Wei WANG <wei_wang@realsil.com.cn> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
