mmc: sdhci: add 64bit addressing support

- Configure ADMA_ADDRESS_HI register if controller version
  is 4.0 and supports 64 bit DMA addressing
- Set HOST_VERSION_4_EN and ADDRESSING_64BIT_EN bits of HOST_CONTROL2
  register for controller version >4.00 in sdhci_reset().
- If len < 4, the extra transfer for alignment can do all job.
  No need to creating another descriptor for aligned transfer.
- Select ADMA2 for DMA_SELECT in Host control register if
  controller version is 4.0 or more.
