DDR52 speed mode is enabled for eMMC in J7200 but its Itap Delay Value
is not present in the device tree. Thus, add Itap Delay Value for eMMC
High Speed DDR which is DDR52 speed mode for J7200 SoC according to
datasheet for J7200 [1].

[1] Refer to : section 7.9.5.16.1 MMCSD0 - eMMC Interface,  in
	J7200 datasheet
