Add i.MX8ULP EVK basic support, support SD/I2C/ENET/LPUART

Log as below: I would keep some debug info for now, and after we move
to be stable and production launch, we could drop that.

When booting from boot part1/2, the image offset should be 0, but
ROM has a bug to return 0x8000. Has to workaround the issue before
ROM fix it.

Use a ROM function to know boot from emmc boot part or user part
So we can set the image offset accordingly.

Since CMC1 MR0 only reflects high 16 bits boot cfg used for AP domian,
it does not connect to low 16 bits for RTD. So we can't get the correct
boot mode.
Change to use DGO_GP5 of SEC_SIM which is set by ROM.

The CMC1 SRS reflects the current reset cause, not SSRS.

Then you could get "Reset cause: WARM-WDG" when issue reset in U-Boot.

This driver uses FSB to read some fuses, but not support program fuse.
It only works in SPL (secure mode), u-boot needs traps to ATF to
read them.

Since S400 will set the memory of SPL image to R/X. We can't write
to any data in SPL image.

1. Set the parameters save/restore only for u-boot, not for SPL. to
   avoid write data.
2. Not use MU DM driver but directly call MU API to send release XRDC
   to S400 at early phase.
3. Configure the SPL image memory of SRAM2 to writable (R/W/X)

SRAM2 is half L2 cache and default to SRAM after system boot.
To enable the full l2 cache (512KB), it needs to reset A35 to make
the change happen.

So re-implement the jump entry function in SPL:
1. configure the core0 reset vector to entry (ATF)
2. enable the L2 full cache
3. reset A35
So when core0 up, it runs into ATF. And we have 512KB L2 cache working.
