When sd/mmc work at DDR mode, like HS400/HS400ES/DDR52/DDR50 mode,
the output clock rate is half of the internal clock rate.

This patch set the DDR_EN bit first for DDR mode, hardware divide
the usdhc clock automatically, then follow the original sdr clock
setting method.

Since the introduction of the driver, some memory in IRAM is reserved for
the TX buffers.

However there are not used but instead of it, it is the buffer provided
by the net stack which is used. As stated in the comment of the driver,
not using the IRAM buffer could cause cache issue and lower the
throughput.

For the second argument it is less the case for transmitting buffers
because the throughput gain in IRAM is mitigated by the time to copy the
data from RAM to IRAM, but the first argument is still valid and indeed

btrfs_search_tree should return the first item in the tree that is
greater or equal to the searched item.

The search algorithm did not properly handle the edge case where the
searched item is higher than the last item of the node but lower than
the first item of the next node. Instead of properly returning the first
item of the next node, it was returning an invalid path pointer
(pointing to a non-existent item after the last item of the node + 1).

This fixes two issues in the btrfs driver:
  - Looking for a ROOT_ITEM could fail if it was the first item of its
    leaf node.
  - Iterating through DIR_INDEX entries (for readdir) could fail if the
    first DIR_INDEX entry was the first item of a leaf node.

ROOT_ITEMs in btrfs are referenced without knowing their actual "offset"
value. To perform these searches using only two items from the key, the
btrfs driver uses a special "btrfs_search_tree_key_type" function.

The algorithm used by that function to transform a 3-tuple search into a
2-tuple search was subtly broken, leading to items not being found if
they were the first in their tree node.

This commit fixes btrfs_search_tree_key_type to properly behave in these
situations.
