HSMMC:Set disable timeout to 1ms

The disable timeout is reduced from 100ms to 1ms in order
to obtain aggressive power saving.

MMC: OMAP HSMMC: Enable Auto CMD12

Configure OMAP HSMMC module to support Auto CMD12.
This will increase throughput during multi-block
command operations as CMD12 does not have to be
explicitly sent each time by software intervention.
Instead, hardware will send CMD12 after desired
number of blocks are transferred.

omap4-hsmmc : Adding ADMA support

Adds ADMA support for HSMMC controllers 1 & 2 on OMAP4
Ensure dma-sg list coming from block layer is unmapped after
every transfer completion.

mmc: omap: align adma and dma table entries

mmc->max_segs to core layer was set to 1024, but
adma table entry could only hold 512 entries. Increase
adma table entry size to 1024 from 512 to avoid mismatch.

Also set max_blk_count, max_req_size to what adma can
handle.

mmc: omap: Increase number of blks we can handle

The above block layer is doing a "min" of max_req_size
and max_blk_count*512 before submitting each request.

As a result, the maximum size of request we are getting
is only 120*512 = 60KB even though each line in the
ADMA table can handle can handle that data alone.

So, we increase the max_blk_count we can handle. Also,
note that worst case is when above block layer gives
us 512 segments, in which there are 511 single block
entries, but one large block that is of size
mmc->max_req_size - (511*512) bytes.

In this case, we use the reserved 512 table entries
to break up the large request. Also adjust the
max_segs accordingly.

omap-hsmmc: Implementation of i761 errata

Errata description:
Due to a bad behavior of an internal signal, the Card Error interrupt bit
MMCHS_STAT[28] CERR may not be set sometimes when an error occurred in the
card response.

Workaround:
After responses of type R1/R1b for all cards and responses of type R5/R5b/R6
for SD and SDIO cards, software must read two registers: MMCHS_RSP10 and
MMCHS_CSRE. When a MMCHS_CSRE[i] bit is set to 1, if the corresponding bit at
the same position in the response MMCHS_RSP10[i] is set to 1, the host
controller indicates a card error and software should proceed in the same way
as if a CERR interrupt would have been detected in the MMCHS_STAT register.

Note:
This errata is applicable for omap44xx.

Tweaked SIO for the new omap hsmmc driver

Quote from my XDA thread:
But here comes the awesomeness: I have pulled updates for the hsmmc driver
(high speed multimedia card; the Tuna's 'harddrive controller' if you will)
from the Texas Instruments repo. While I noticed an initial improvement of
many apps' loading times, I began to tweak the SIO scheduler and got to a
point where... Oh well. See for yourselves.
