[PATCH 1/4] arm64: dts: ti: k3-am62p5-sk: Disable MMC1 internal pulls on data lines

[Judith Mendez]

AM62p SK has external pullups on DATA 1-3 pins [0]. Remove internal
pullups considering:
- having both internal and external pullups reduces the total pull-up
  resistance < 10K resulting in unnecessary power consumption
- mismatched pullup resistace between D0 and D1-D3 may cause potential
  issues for modes with tighter timing requirements. The different pull-up
  values cause different rise/fall times on each data line.
