ENGR00142322: mx53-smd: spi nor: can't erase 0x200000 sizerel_imx_2.6.35_11.04.01imx_v2009.08_11.04.01
Spi nor can't erase 0x200000 size.
There are two issues in this CR.
1. Spi nor can't erase 0x200000 size.
2. Whole chip erase don't work.
The solution will be:
1. Delay more time for WIP check.
2. Use normal erase for whole chip erase.
