nand: Make NAND lock status compatible with Micron

Micron NAND flash (e.g. MT29F4G08ABADAH4) BLOCK LOCK READ STATUS is not
the same as others.  Instead of bit 1 being lock, it is #lock_tight.
To make the driver support either format, ignore bit 1 and use only
bit 0 and bit 2.

cmd_nand: fix crashing bug in nand read/write

Commit 418396e212b59bf907dbccad997ff50f7eb61b16 introduced a
bug that causes nand read and nand write to crash in strcmp
due to a null pointer.

Root cause is that strchr(cmd, '.') returns a null pointer when
the input string does not contain a '.'

The strcmp function does not check for null pointers, resulting
in a crash.

A use for this is to read, modify, erase, and write an entire block as a
single unit, as a replacement for the biterr command.  This way gives
more flexibility in that you can also test multiple bit errors, errors
in the ECC, etc.
