mtd: nand: disable subpage reads ...

The default nand_read_subpage implementation returns -ENOSUPP, so we have
to make sure that barebox never uses this implementation. By setting the
NAND_SUBPAGE_READ flag to 0x0 we ensure NAND_HAS_SUBPAGE_READ() never returns
true and also give the compiler a chance to optimize away some unused code.

subpage reads are a rather exotic feature even in Linux. It is only used on
largepage NANDs with soft ecc. Even if we have this case it needs non page
aligned reads to actually profit from this feature.

mci: Fix version handling ...

Currently the version defines reflect the digits in the version
number. MMC_VERSION_4_41 is defined as 0x441 and MMC_VERSION_4_5
is defined as 0x405. This results in MMC_VERSION_4_5 < MMC_VERSION_4_41
becoming true which was surely not intended. Fix this by
redefining the versions as 0x<major><minor><micro>. This makes the
string generation more complicated but makes versions comparable
again.

console: Set Linux console parameter automatically ...

Linux specifies the linux,stdout-path property in the /chosen node
in the devicetree. Unfortunately this is ignored in most cases.
For cases in which barebox uses this property for its own use we
translate this into a Linux boot arg with:

- the console name provided by the serial driver
- the the instance from the 'serial' alias
- the baudrate from the actual baudrate.

So with this it's for devicetee enabled boards no longer necessary
to manually assign a console= parameter. Should a user not want
to use the automatically assigned parameter it should do:

global.linux.bootargs.console=

in the environment.

mci: add DSR support ...

The eMMC and the SD-Card specifications describe the optional SET_DSR command.
During measurements at our lab we found that some cards implementing this feature
having really strong driver strengts per default. This can lead to voltage peaks
above the specification of the host on signal edges for data sent from a card to
the host.

Since availability of a given card type may be shorter than the time a certain
hardware will be produced it is useful to have support for this command (Alternative
would be changing termination resistors and adapting the driver strength of the
host to the used card.)

eMMC is available up to version 4.5 but the
correct version is not decoded. Change version

After this, card detection code and devinfo reports
correct versions.

Handling is inspired by u-boot code.
