msm: msm_sdcc: fix data/cmd CRC errors during SDR104 mode operation

SDR104 mode requires DLL (Delay locked loop) HW block to be tuned
as clock rate is greater than 100MHz. But we observed multiple CMD
CRC errors while erasing the SD card and DATA/CMD timeout errors
while writing/reading on to SD card if it's running in SDR104 bus
speed mode (SD clock rate @192MHz).

DLL has a mechansim of data tracking (CDR) which can be enabled
during RX transaction so the host will not lose the sampling point.
CMD19 (tuning pattern command) can be sent automatically before
any RX transaction for helping the CDR to track after the correct
sampling point.

But if this data tracking is kept enabled during TX transactions then
it may cause the DATA/CMD CRC errors during TX transactions. So this
patch ensures that data tracking is only enabled during RX transactions
and remains disabled for TX transactions.

In addition to this change, it is found that DLL valid phase windows
may be cyclic so this patch also ensures that 2 different valid phase
windows are treated as single valid window if it's cyclic.
