The u-boot of i.MX6ULL chip needs header data.The update_nand.c will
add header data when writing into NAND flash.
These code reference from Digi ccimx6ul.

VGEN3 and VGEN5 have been fused the right value in PF0100 on i.mx6qp board,
so software didn't need to change their voltage output anymore. Otherwise,
VGEN3 will be wrongly updated from 1.8v to 2.8v.

We found a issue in PLL6 ENET that changing the bit[1:0] DIV_SELECT for ENET
ref clock will impact the SATA ref 100Mhz clock. If SATA is initialized before
this changing, SATA read/write can't work after it. And we have to re-init SATA.
The issue can reproduce on both i.MX6DQP and i.MX6DQ. IC investigation is ongoing.
This patch is an work around that moves the ENET clock setting
(enable_fec_anatop_clock) from ethernet init to board_init which is prior
than SATA initialization. So there is no PLL6 change after SATA init.

Add configs and board level codes for i.MX6ULL 14x14 EVK. Very similar
board from i.MX6UL EVK. I2C, UART, USB, QSPI, SD, ENET and LCD are ok
to work.
The codes for i.MX6ULL 9x9 EVK is kept. We will add 9x9 build target when
it is needed.
The DDR3 script is using version 1.2:

In u-boot, i.MX6QP sabresd board uses 125Mhz ref clock from PHY,
While kernel uses the clock from internal PLL by setting GPR5 bit 9.
When doing warm reset in kernel, the GPR regigster is not reset, so
the clock source still is the PLL. This causes ENET in u-boot can't work.
In this patch, we change the u-boot to use internal PLL to align with
kernel for i.MX6QP. This also fixes the ENET issue after kernel warm reset.

On i.MX7D lpddr3, retention mode exit flow should restore
more registers to make sure the ddr controller and ddr phy
settings restored properly, otherwise, some of the boards
can NOT pass memtester after retention mode exited.
For LPSR mode, ddr resume flow is same as retention mode,
just adjust it accordingly.

Since the CD pin of SD2 is DNP on the mx6ull arm2 board, this will cause
SD2 access problem even the card is inserted. Hard code the CD result to
1 to assume the card is always on.
The SD driver will return other errors if the card does not exist.
