Fix RPi4 VL805 USB controller flashing for W25X10 chips to RDID4
This patch is simple, it helps change id 72057 to work on a Raspberry Pi 4 Model B, by changing the W25X10 flash chip from RDID to RDID4, to flash with the VL805 controller. If this patch is not applied, then this error will come up: "Found Generic flash chip "unknown SPI chip (REMS)" (0 kB, SPI) on vl805." else it detects the 128 kB flash chip just fine.
