arm64: dts: ti: am62-verdin: Enable pullup for eMMC data pins
Verdin AM62 board does not have external pullups on eMMC DAT1-DAT7 pins.
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, 10kohm-150kohm per JEDEC), which may
exceed the recommended 50kohm max for 1.8V VCCQ
- JEDEC JESD84-B51 Table 200 requires host-side pullups (R_DAT,
10kohm-100kohm) on all data lines to prevent bus floating
