[PATCH] arm: dts: k3-j721e-main: Update the speed modes supported and their itap delay values for MMCSD subsystems
According to latest errata of J721e [1], HS400 mode is not supported in MMCSD0 subsystem (i2024) and SDR104 mode is not supported in MMCSD1/2 subsystems (i2090). Therefore, replace mmc-hs400-1_8v with mmc-hs200-1_8v in MMCSD0 subsystem and add a sdhci mask to disable SDR104 speed mode.
Also, update the itap delay values for all the MMCSD subsystems according the latest J721e data sheet[2]

Please ignore this patch, the fixes tag that I have used is not the correct one. Will fix it and post a respin. Sorry about the noise.
Thanks, Aswath
