Cooper Jr., Franklin 6e1eb089be mtd: nand: am335x_spl_bch: Incorporate tWB delay in nand_command function 
Various commands to NAND flash results in the NAND flash becoming busy.
For those commands the SoC should wait until the NAND indicates it is
no longer busy before sending further commands. However, there is a delay
between the time the SoC sends its last command and when the NAND flash
sets its Ready/Busy Pin. This delay (tWB) must be respected or the SoC may
falsely assume the flash is ready when in reality it just hasn't had enough
time to indicate that it is busy.

Properly delaying by tWB is already done for nand_command/nand_command_lp
in nand_base.c including the version of it in the Linux kernel. Therefore,
this patch brings the handling of tWB delay inline to nand_base.c
