mtd: ubi: remove now unused ioctls ...

The only ioctl needed is the one to get the ubi_num from a file
descriptor. The remaining ioctls are now implemented as regular
function calls.

mtd: ubi: Add API calls to create/remove volumes ...

Currently we use a ioctl API to create/remove ubi volumes. This
means we always have to carry all function code for ubi volume
manipulation when the ioctl is compiled in.
This adds a function API to create/remove volumes so that the linker
can throw the unused code away later.

mci: mmci: Fix read FIFO handling ...

According to the Linux kernel and the qemu code, the MMCIFIFOCNT contains
the remaining number of words to read, excluding those that are already in
the FIFO. So the current number of bytes in the FIFO is
host_remain - (readl(base + MMCIFIFOCNT) << 2).

Also writing to MMCIDATACTRL will reset the read counter. As a result,
MCI_DATABLOCKEND is never set and read_bytes() waits forever.

With this change, SD-Card support on qemu vexpress works correctly.

So far we relied on the clock rate as configured by reset default or
board code. Also we did not touch the symmetric mode bit. Use
the ONFI provided timing parameters to configure the clock rate for
the Nand controller. Also symmetric mode (EDO mode) when needed.
This is done for v2 controllers (i.MX25/35) only, other controllers
need other setup code.
