NAND finally working. Two bugs fixed:
...
* For READ_STATUS and READID commands always 8 bytes need to be read from
NDDB. Otherwise they stay there and get send to flash as the first data
word when writing.
* In nand_base.c the oob variable is not reset so this->oob_buf is
overwritten what eventually screws up the bad block descriptor table.

Lots of new stuff:
...
* Debug message can be turned on and off.
* Waiting for events now times out.
* Implemented RESET command.
* Added appropriate nand_bbt_descriptor and nand_oobinfo.
Remaining Problems:
* Read Status still behaves weird an returns invalid stuff sometimes.
* ECC Placement does not respect our scheme in nand_oobinfo.

Erasing works too now. The CS don't care causes problem with READSTATUS,
...
don't ask me why. There are still bugs in the bad block logic.

Write operation is working. Turned out that the READSTATUS hack was wrong
...
after all.

Writing is working, but there's still a bug that causes the data written to
...
start at an offset of 4 bytes from the start of the page.

Moved the waiting loop for "Read Data Request" RDDREQ into the
...
delta_cmdfunc function, because this bit is only set once after a command
is sent and this allows read functions to be called multiple times.

Read bug fixed. Now "nand bad" list the badblocks correctly (i hope, since
...
there are 0)

Further NAND stuff implemented. Basic read commands seem to work.

First steps implementing NAND support. Not working, fails to read ID.
