Bao D. Nguyen 7c24cb15cb ARM: dts: msm: Add SD card LS external feedback clock support ...

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.
