There have two same extended enet dts file to enable fec2 port, so

MMC core pm_notify will re-detect card after system suspend/resume,
regardless of post-cd claim.
Since in current MMC implement, non-removeable card only detects once,
this will break post card detect which happens next.
e.g. when we suspend/resume system first, then load Broadcom wifi module,
we will get below dump:root@imx6qdlsolo:/mnt/nfs/vte_IMX6QP-Sabre-SD# modprobe bcmdhd firmware_path=/lib/firmware/bcm/ZP_BCM4339/fw_bcmdhd.bin nvram_path=/lib/firmware/bcm/ZP_BCM4339/bcmdhd.ZP.SDIO.cal

Before entering LPSR mode, as GPC was set to STOP/DSM mode already,
the wfi loop after LPSR mode would cause system enter STOP/DSM mode
first, then SNVS will force PMIC_ON_REQ to low, as SNVS needs IPG
clock to be on before entering SNVS/LPSR mode, so we have to disable
STOP/DSM mode to make sure IPG clock is on before SNVS actually enters

In .mdio_bus_phy_may_suspend(), there check netdev is NULL to judge to set
phy to suspend status.netdev is NULL has three cases:
- phy is not found
- phy is found, match to general phy driver
- phy is found, match to specifical phy driverCase 1: phy is not found, cannot communicate by MDIO bus.
Case 2: phy is found:
if phy dev driver probe/bind err, netdev is not __open__ status,
mdio bus is unregistered.
if phy is detached, phy had entered suspended status.
Case 3: phy is found, phy is detached, phy had entered suspended status.So, in here, it shouldn't set phy to suspend by calling mdio bus.
In i.MX6UL evk/arm2 board, if down the ethx interface and do suspend/resume,
system will hang. Because after ethx down all clocks are gated off, for general
phy driver, unbind the phy device, for specifical phy driver, no unbind the
device, and the original driver call mdio bus to set phy to suspend during
system suspend, so system will hang since there have mdio register access.
The patch can fix it.Signed-off-by: Fugang Duan

bcmdhd can't support removing host during suspend and

It looks bcmdhd has a special requirement to enumerate card

as it wants, then we add back non-removable capability
