This patch adds MMC over SPI support to mci-core.c and
mci_spi.c driver.
This driver is useful when SOC doesn't have built-in MCI
component. Tested with nios, 2Go SD-CARD and FAT file system.

fat_stat in fs/fat.c declares finfo but doesn't initialize it.
When get_fileinfo is called, fno->lfname and fno->lfsize are
tested but haven't been zeroed...This can lead to a wrong
behavior.

Now that we have multi block read and write this is not necessary

Mount without argument always print a "none" as device name mounted
because entry->parent_device is always NULL.
The problem is the mount function in fs/fs.c. parent_device is
initialized to NULL and never updated. With this patch,
parent_device is set with the mounted device name.
Moreover, the mount function has been modified to print the device
name plus device id using the dev_name function.

Currently, there are multiple definitions of run_shell()
for each board that can be build in "xload" configuration.
Now there is only one function used by all boards.
The functions defined in xload.c are used only when "xload"
configuration used; but it gets compiled unconditionally.
This has been fixed as well.

We can't use the ECC_RESULTx_0 register set for manual mode which
