Change CFG_ENV_SIZE to CFG_ENV_SECT_SIZE for SPI sector erase
The CFG_ENV_SIZE is not suitable used for SPI flash erase sector size if CFG_ENV_SIZE is less than CFG_ENV_SECT_SIZE. Add condition check if CFG_ENV_SIZE is larger than CFG_ENV_SECT_SIZE, calculate the right number of sectors for erasing. Signed-off-by: TsiChung Liew <Tsi-Chung.Liew@freescale.com>
