arm64: dts: ti: k3-am62-lp-sk: Enable internal pulls for MMC0 data pins
AM62 LP SK board does not have external pullups on MMC0 DAT1-DAT7
pins [0]. Enable internal pullups on DAT1-DAT7 considering:
- without a host-side pullup, these lines rely solely on the eMMC
device's internal pullup (R_int, 10-150K per JEDEC), which may
exceed the recommended 50K max for 1.8V VCCQ
- JEDEC JESD84-B51 Table 200 requires host-side pullups (R_DAT,
10K-100K) on all data lines to prevent bus floating
