sf: Remove spi_flash_cmd_poll_bit()
There is no other call other than spi_flash_cmd_wait_ready(), hence removed spi_flash_cmd_poll_bit and use the poll status code spi_flash_cmd_wait_ready() itself. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com> Reviewed-by: Simon Glass <sjg@chromium.org>
