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.
