Add Support for eMMC in TI's AM65x-evm. The series starts
by syncing the sdhci0 node from the kernel. Then it adds APIs and
changes to the driver required for handling the driver's integrated
phy. The current maximum supported speed is DDR52. Higher speeds and
tuning support will be added in a subsequent series.

Tested with Andreas's latest series[1] on top. Can be applied
independently of that series though.

Changes in v7:
Fixed a device tree entry in patch 1 and tested eMMC boot as well
with Andreas's latest series[1].

Changes in v6:
1. Squashed one more dependency for clk_200mhz from Andreas's patches[1]
   into patch 1. Patches now build without any help from the other series.

2. Improved line wrapping in patch 8.

Changes in v5:
Patches were tested with Andreas's system firmware patches[1] but can now be
independently merged cleanly on latest U-boot.

Changes in v4:
1. Dropped the patch including regmap_read_poll_timeout() because that support was
   already added by someone else
2. Fixed a NULL pointer exception in patch 8.
3. Rebased on top of latest master
4. Added extra patches to support GPT partitions in user partition
5. Added Support for environment in eMMC by default

Changes in v3:
Patch 9: Got rid of variable ret

Changes in v2:
Patch 9: Fixed return value
Patch 12: Fixed spacing
