This reverts commit 39768f77.

Reson: it breaks a number of boards with embedded environment as the
code size grows in some places.

8xx was left behind when fixing up powerpc linking
scripts to support -fpic.

The omap24xx driver only seems to support devices that have a single subaddress
byte. With these types of devices, the first access in a bus transaction is
usually a write (writes the subaddress) followed by either a read or write to
access the devices registers.

Many such devices will respond to a read as the first access, but there are at
least some that will NACK such a read. (e.g. ADV7180.)

The probe function attempts to detect a devices ACK to a read access only and
fails to find devices that NACK a read.

This commit modifies the probe function to start a write instead. This detects
devices that respond to reads (since they must also respond to writes) as well
as those that only respond to writes. The bus is immediately set to idle after a
(N)ACK avoiding actually writing anything to the device.

Finally I think that it is enough to apply the following patch in order
to fix the issue.

The first SEND_OP_COND (CMD1) command added is used to ask card capabilities.
After it an AND operation is done between card capabilities and host
capabilities (at the moment only for the voltage field).
Finally the correct value is sent to the MMC, waiting that the card
exits from busy state.

It is recommended to check card status after these kind of commands.
This is done using CMD13 (SEND_STATUS) JEDEC command until
the card is ready.
In case of error the card status field is displayed.

This patch supports mmc/sd card with spi interface. It is based on

As DATA_ERROR includes the value IRQSTAT_DTOE, a timeout error
would yield the first error return instead of TIMEOUT.
By swapping the test TIMEOUTs are reported as such

An alternate solution would be to remove the IRQSTAT_DTOE from the DATA_ERROR define
but as that one might be less desired I've opted for the simplest solution

The maximum blocks value was hardcoded to 65535 due to a 16 bit
