eMMC 5.1+ supports HS400 Enhances Strobe mode without the need for
tuning procedure.
The flow is as following:
 - set HS_TIMIMG (Highspeed)
 - Host change freq to <= 52Mhz
 - set the bus width to Enhanced strobe and DDR8Bit(CMD6),
   EXT_CSD[183] = 0x86 instead of 0x80
 - set HS_TIMING to 0x3 (HS400)
 - Host change freq to <= 200Mhz
 - Host select HS400 enhanced strobe complete

The mmc_spi command was added to manually setup MMC over SPI bus
using command. This was required by the legacy non-DM MMC_SPI driver.

With DM based MMC_SPI driver in-place, we can now use all general
storge commands and mmc command for MMC over SPI bus hence we remove
the mmc_spi command all it's references.

Accessing the boot partition had been error prone with HS200 and HS400 and
was disabled. The driver first switched to a lesser mode and then switched
the partition access. It was mostly due to a bad handling of the switch and
has been fixed, so let's remove this 'feature'

The switch operation can sometimes make the bus unreliable, in that case
the send_status parameter should be false to indicate not to poll using
CMD13. If polling on dat0 is possible, we should use it to detect the end
of the operation.
At the end of the operation it is safe to use CMD13 to get the status of
the card. It is important to do so because the operation may have failed.

The e-MMC spec allows the e-MMC to specify a timeout for the partition
switch command. It can take up to 2550 ms. There is no lower limit to this
value in the spec, but do as the the linux driver does and force it to be
at least 300ms.

Using the DAT0 line as a rdy/busy line is an alternative to reading the
status register of the card. It especially useful in situation where the
bus is not in a good shape, like when modes are switched.
This is also how the linux driver behaves.

Note of warning: As per the specification, while polling on DAT0 the CLK
must not turned off: "[...] Without a clock edge the Device (unless
previously disconnected by a deselect command (CMD7)) will force the DAT0
line down, forever. [...]"

mmc_send_status() is currently used to poll the card until it is ready, not
actually returning the status of the card.
Make it return the status and add another function to poll the card.

Also remove the 'extern' declaration in the mmc-private.h header to comply
with the coding standard.

This is not required. The MMC core sends CMD0 right after the
initialization and it serves the same purpose.

It sometimes happen that the PSTATE register does not indicate that the
bus is ready when it really is. This usually happens after a mode switch.
In that case it makes sense to reset the FSM handling the CMD and DATA

Also reset the FSMs if the STATE register cannot be cleared. This also
sometimes happens after a mode switch.

Signed-off-by: NAdam Ford <aford173@gmail.com>

With a recent update to the pinctrl-single driver and the fact
that the da850evm has both DM and OF_CONTROL working in both SPL
and U-Boot, some of the manual pinmuxing can be setup to only
be activated when either the driver doesn't have DM for it, or
when CONFIG_PINMUX isn't available (only during SPL).  If the
code ever shrinks enough to support PINCTRL in SPL, a lot of this
can go away.  This also remove some manual pinmuxing not needed
by SPL to give SPL a little more breathing room.

The USE_TINY_PRINTF symbol only changes things within SPL and TPL
builds, so make it depend on that support.  Next, make it default as
within these cases we should rarely have need of more advanced print
formats outside of the debug context.

To do this, in a few cases we need to correct our Kconfig dependencies
as we had cases of non-SPL targets select'ing this symbol.  Finally, in
the case of a few boards we really do need the full printf
functionality.
