[U-Boot] [PATCH 01/10] imx8m: imx8mq: get chip rev for B1 revision

[Peng Fan]

The i.MX8MQ B1 uses OCOTP_HW_OCOTP_READ_FUSE_DATA register for chip id.
It returns a magic number 0xff0055aa. update get_cpu_rev to support it,
and enable ocotp clock to access ocotp.

[U-Boot] [PATCH 03/10] imx: imx8mq: add init_nand_clk

[Peng Fan]

Add init_nand_clk to enable gpmi nand clock. Since i.MX8MQ not use CCF,
so we still use legacy mode to configure the clock.

It will be easy to separate SD/EMMC when booting in SPL stage, then
no need to bother which device is BOOT_DEVICE_MMC1/2.

[U-Boot] [PATCH 09/10] imx8m: evk: spl: probe clk in spl early stage

[Peng Fan]

We are going to add i2c pmic support before dram could be used.
So we need enable clk driver earlier, so use spl_early_init
and move clock controller probe eariler to board_init_f.
