sf: Add flag status register polling support Flag status register polling is required for micron 512Mb flash devices onwards, for performing erase/program operations. Like polling for WIP(Write-In-Progress) bit in read status register, spi_flash_cmd_wait_ready will poll for PEC(Program-Erase-Control) bit in flag status register.
