spi_flash: Fixed bug in SPI flash ROM driver to work with embedded flash chip 1) fixed SPI_read_status: added check for flash busy flag in matrix mode 2) fixed SPI_page_program: enable write before writing data to SPI FIFO 3) SPI flash ROM funcs replacement is controlled via menuconfig option

spiflash ROM functions: Remove Quad I/O mode enable/disable code from flash ROM functions Confusion here is that original ROM has two functions: * SPIReadModeCnfig() - sets mode, calls enable_qio_mode/disable_qio_mode * SPIMasterReadModeCnfig() - As above, but doesn't set QIO mode in status register However we never want to use the ROM method to set/clear QIO mode flag, as not all flash chips work this way. Instead we do it in flash_qio_mode.c in bootloader. So in both cases (ROM or "patched ROM") we now call SPIMasterReadModeCnfig(), which is now named esp_rom_spiflash_config_readmode().
