OMAP2PLUS and BCM283X mmc controllers do not work correctly with new emmc code which reads partition access bits prior mmc controller reset.

So introduce a new config option MMC_ENABLE_PART_ACCESS, which is by default disabled for ARCH_OMAP2PLUS and ARCH_BCM283X; and selected for 32-bit mvebu mmc booting (which requires it).

•  Read partition access bits from partition config register before card reset command
  

•  because these bits are reset to default value (User Data Area) during card reset.
  

•  This allows us to preserve original value of partition access bits used by the code
  

•  which loaded us (for example BootROM) and use it for board specific boot purposes.
  

•  .
  

•  This is required when U-Boot is using EXT_CSD_EXTRACT_PARTITION_ACCESS macro.
