[U-Boot] [PATCH 33/34] MTD: mxs_nand_spl: Redo the way nand_init initializes

[sbabic at denx.de]

> Currently the spl system calls nand_init which does nothing.
> It isn't until an attempt to load from NAND that it gets initialized.
> Subsequent attempts to load just skip the initialization  because
> NAND is already initialized.
> This moves the contents of mxs_nand_init to nand_init.  In the event
> of an error, it clears the number of nand chips found.  Any
> attempts to use nand will check if there are nand chips available
> instead of actually doing the initialization at that time. If there
> are none, it will return an error to the higher level calls.
