[U-Boot] [PATCH 1/5] mtd: spi-nor: fix page program issue when using spi-mem driver

Some SPI controllers can't write nor->page_size bytes in a single step because their TX FIFO is too small, but when that happens we should make sure a WRITE_EN command before each write access and READ_SR command after each write access is issued. We should allow nor->write() to return a size
