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.

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.

CONFIG_SECURE_BOOT is too generic and forbids to use it for cross
architecture purposes. If Secure Boot is required for imx, this means to
enable and use the HAB processor in the soc.

Because we need to get cpu freq in print_cpuinfo at very early stage,
so we need to make sure the ccm be probed.

Introduce clk implementation for i.MX8MM, including pll configuration,
ccm configuration. Mostly will be done clk dm driver,
but such as DRAM part, we still use non clk dm driver, because we
have limited sram.

i.MX8MQ and i.MX8MM use different analog pll design, but they
share same ccm design.
Add clock_imx8mq.h for i.MX8MQ
keep common part in clock.h

i.MX8MQ and i.MX8MM has totally different pll design, so
rename clock to clock_imx8mq.

To i.MX8MM SCTR clock is disabled by ROM, so before timer init
need to enable it.
To i.MX8MQ, it does not hurt the clock is enabled again.

Set trustzone region 0 to allow both non-secure and secure access
when trust zone is enabled. We found USB controller fails to access
DDR if the default region 0 is secure access only.

When running with OPTEE, the MMU table in u-boot does not remove the OPTEE
memory from its settings. So ARM speculative prefetch in u-boot may access
that OPTEE memory. Due to trust zone is enabled by OPTEE and that memory
is set to secure access, then the speculative prefetch will fail and cause
various memory issue in u-boot.
The fail address register and int_status register in trustzone has logged
that speculative access from u-boot.

There is no HDMI on i.MX8MM, so we need to remove HDMI entry, then
we could not reuse imximage.cfg, so create a new one.

OSC_27M_CLK should return 27MHz and OSC_32K_CLK should return
32768Hz to reflect the reality.
This also keeps the values in sync with the Linux clock tree.

Add i.MX8MQ EVK support. SPL will initialize ddr and load ddr phy
firmware. Then loading FIT image, ATF to OCRAM, U-Boot and DTB to
DRAM.
