Recent changes to the nand_imx driver broke it for i.MX21 systems;
the i.MX21 NAND controller is more akin to the one in i.MX27/i.MX31,
than to the one in i.MX25/i.MX35.

Our version of ppc bitops produces the following compiler warnings:

warning: '__swab32p' is static but used in inline function 'ext2_find_next_zero_bit' which is not static
Looking at the kernel ext2_find_next_zero_bit is defined as
generic_find_next_zero_le_bit which is in generic kernel code.
We currently do not need this, so do the very same define to silence the
compiler. If somebody ever needs this function, the resulting error
should give him a hint what to do.

Due to the lack of hardware the 16 MiB and 128 MiB case is untested yet.
Due to the 32 MiB configuration we must link the u-boot-v2 always to
