This patch defines get_dctrl_cfg callback for qcom variant.
qcom variant has a specific block size definition.

Having mmci_dmae_start() to invoke the shared function, dml_start_xfer(),
explicitly for the qcom variant isn't very nice. Let's clean up this code
by moving the qcom specific parts into the qcom ->dma_start() callback and
then drop dml_start_xfer() altogether.

There's no point clearing the variant flag in case the qcom variant fails
to setup DMA. This is because if mmci_dma_setup() fails, then the use_dma
flag remains set to false, which leads to mmci using PIO mode and not DMA.

This patch creates a common mmci_dma_setup/release which calls
dma_setup/release callbacks of mmci_host_ops and manages
common features like use_dma... If there is a fallbacks to
pio mode, dma functions must check use_dma.
error management:
-mmci_dmae_setup fail if Tx and Rx dma channels are not defined
-qcom_dma_setup fail if one of both dma channels is not defined,
Qcom has no specific resource to release, just mmci dmae resource.

As a first step to improve the variant specific code for mmci, add a
->dma_setup() callback to the struct mmci_host_ops.
To show its use, let's deploy the callback for the qcom dml, which involves
also to the assign the mmci_host_ops pointer from the variant ->init()
callback.

Fix typos and add the following to the scripts/spelling.txt:
intialization||initialization
The "inintialization" in drivers/acpi/spcr.c is a different pattern but
I fixed it as well in this commit.

On Qualcomm APQ8064 SOCs, SD card controller has an additional glue
called DML (Data Mover Local/Lite) to assist dma transfers.
This hardware needs to be setup before any dma transfer is requested.
DML itself is not a DMA engine, its just a gule between the SD card
controller and dma controller.
Most of this code has been ported from qualcomm's 3.4 kernel.
This patch adds the code necessary to intialize the hardware and setup
before doing any dma transfers.
