Add patches for linux-5.4. The patches are from NXP LSDK-20.04 release which was tagged LSDK-20.04-V5.4. https://source.codeaurora.org/external/qoriq/qoriq-components/linux/ For boards LS1021A-IOT, and Traverse-LS1043 which are not involved in LSDK, port the dts patches from 4.14. The patches are sorted into the following categories: 301-arch-xxxx 302-dts-xxxx 303-core-xxxx 701-net-xxxx 801-audio-xxxx 802-can-xxxx 803-clock-xxxx 804-crypto-xxxx 805-display-xxxx 806-dma-xxxx 807-gpio-xxxx 808-i2c-xxxx 809-jailhouse-xxxx 810-keys-xxxx 811-kvm-xxxx 812-pcie-xxxx 813-pm-xxxx 814-qe-xxxx 815-sata-xxxx 816-sdhc-xxxx 817-spi-xxxx 818-thermal-xxxx 819-uart-xxxx 820-usb-xxxx 821-vfio-xxxx Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>
