Add the Level Shifter's external feedback clock entry to support the SD card HS50 mode running at 50MHz. By default, the Sun platforms use the Level Shifter devices with external feedback clock signal connects back to the MSM in order for the HS50 mode to work at 50MHz. Without the external feedback clock, the HS50 mode works at reduced frequency at 37.5MHz. Change-Id: I56c61411d7f792a389fa85661fce7fa5074e2c9f Signed-off-by: Bao D. Nguyen <quic_nguyenb@quicinc.com>
