[PATCH v2 4/5] configs: am62px_evm_r5/a53_defconfig: Disable eMMC HS400

[Judith Mendez]

This patch addresses silicon errata i2458 [0] "MMCHS: eMMC HS400
tDCD timing marginal to JEDEC spec". Where, in some corner cases,
MMC0 interface may marginally exceed the tdCD JEDEC spec requirement
of 300 ps. As per workaround, switch to HS200 mode instead of HS400.
