Xuzhou Cheng 1f4b2ec701 hw/arm: sabrelite: Connect SPI flash CS line to GPIO3_19 
The Linux spi-imx driver does not work on QEMU. The reason is that the
state of m25p80 loops in STATE_READING_DATA state after receiving
RDSR command, the new command is ignored. Before sending a new command,
CS line should be pulled high to make the state of m25p80 back to IDLE.

Currently the SPI flash CS line is connected to the SPI controller, but
on the real board, it's connected to GPIO3_19. This matches the ecspi1
device node in the board dts.

ecspi1 node in imx6qdl-sabrelite.dtsi:
  &ecspi1 {
          cs-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>;
          pinctrl-names = "default";
          pinctrl-0 = <&pinctrl_ecspi1>;
          status = "okay";

          flash: m25p80@0 {
                  compatible = "sst,sst25vf016b", "jedec,spi-nor";
                  spi-max-frequency = <20000000>;
                  reg = <0>;
          };
  };

Should connect the SSI_GPIO_CS to GPIO3_19 when adding a spi-nor to
spi1 on sabrelite machine.

Verified this patch on Linux v5.14.
