mmc: dw_mmc: Replace fifoth_val property with fifo-depth
Replace fifoth_val property with its fifo-depth counterpart in all DW
MMC drivers. fifo-depth is a common property used in upstream Linux
kernel. The FIFOTH register value will be calculated using fifo-depth
value in DW MMC core (dw_mmc.c). This change reduces code duplication in
platform drivers, and pulls common FIFOTH register value calculation
into core dw_mmc driver where it belongs.
No functional change.
