[PATCH V3 1/8] arm64: imx: add imx8qxp support

[aisheng.dong@nxp.com (A.s. Dong)]

i.MX 8QuadXPlus is a quad (4x) Cortex-A35 proccessor. The Cortex-A35
provides full 64-bit ARMv8-A support while maintaining seamless backwards
compatibility with 32-bit ARMv7-A software. Graphics processing is handled
by a dedicated Graphics Processing Unit (GPU) supporting latest graphic APIs.
Video is managed by a dedicated video engine decoding formats, H.265 HEVC
(Main Profile) up to 4K30 and H.264 up to 1080p60, as well as encoding up
to 1080p30. The memory interface supports 32-bit LP-DDR4 without ECC (Error
Correcting Code) protection at 1200 MHz, 40-bit DDR3L with ECC protection at
933 MHz, two FlexSPI , eMMC 5.1, RAW NAND and SD 3.0.

A wide range of peripheral I/Os such as CAN, parallel or MIPI CSI camera
input, Gigabit Ethernet, ADC, USB 2.0 OTG, USB 3.0 and PCIe 3.0 provide
wide flexibility.
