Add i.MX 8M Quad support
- Add CCM driver and clocks implementations for i.MX 8M - Add GPC driver for iMX8 - Add clock tree for i.MX 8M Quad - Add clocks support and new compat strings (where required) for existing i.MX 6 UART, I2C, and GPIO drivers - Enable aarch64-compatible drivers form i.MX 6 in arm64 GENERIC kernel config - Add dtb/imx8 kernel module with DTBs for Nitrogen8M and iMX8MQ EVK With this patch both Nitrogen8M and iMX8MQ EVK boot with NFS root up to multiuser login prompt Reviewed by: manu Differential Revision: https://reviews.freebsd.org/D25274
