On i.MX6ULL, according to the latest REFTOP_TRIM fuse define, we need
to set the REFTOP_VBGADJ bits in PMU_MISC0 register as below table:
'000" - set REFTOP_VBGADJ[2:0] to 3'b000

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:
File: EVK_IMX6ULL_DDR3L_400MHz_512MB_16bit_V1.2_NewDRAM.inc
Test: 3 boards passed memtester.

Several UART input selects are missing. The fourth input select
for UART2_TX_DATA_ALT0 is actually also missing in the documentation.
(at least in Rev. B of the i.MX 7Dual Reference Manual). However,
when looking at the tables of other input selects, it is very natural
that there must be an input select for the UART2_TX_DATA_ALT0 pad.
The Colibri iMX7 also uses that pad for UART2 RX (in DTE mode), and
it was required to set that particular input select register to get a
working UART2.

i.MX6QP and i.MX7D BCH module integrated a new feature to detect the
bitflip number for erased NAND page. So for these two platform, set the
erase threshold to gf/2 and if bitflip detected, GPMI driver will
correct the data to all 0xFF.
Also updated the imx6qp dts file to ditinguish the GPMI module for i.MX6Q
with the one for i.MX6QP.

In this patch, i.MX6UL is added and threshold changed to use ecc_strength.

The clock parent of the AHB root clock when using mux option 1
is the SYS PLL 270MHz clock. This is specified in Table 5-11
Clock Root Table of the i.MX 7Dual Applications Processor
Reference Manual.
While it could be a documentation error, the 270MHz parent is
also mentioned in the boot ROM configuration in Table 6-28: The
clock is by default at 135MHz due to a POST_PODF value of 1
(=> divider of 2).

According PL310 TRM, Auxiliary Control Register
"
The register must be written to using a secure access, and it can be
read using either a secure or a NS access. If you write to this register
with a NS access, it results in a write response with a DECERR response,
and the register is not updated. Writing to this register with the L2
cache enabled, that is, bit[0] of L2 Control Register set to 1,
results in a SLVERR.
"
So If L2 cache is already enabled, chaning value of ACR will cause SLVERR,
uboot hangs.
In some cases, such as plugin, L2 Cache enabled bit is not cleared,
then "Set bit 22 in the auxiliary control register" cause uboot hangs.

2016 u-boot added dummy CPU types for the i.MX6QP and i.MX6DP. When
doing runtime cpu type checking, we can't use CPU type of i.MX6Q and
i.MX6D for them more, which is ok in 2015 u-boot.
This patch adds the MXC_CPU_MX6QP and MXC_CPU_MX6DP at some places missed to
do the checking.

We found when disable CONFIG_VIDEO, all seems fine. Actually,
only the following piece of code can make stress reset ok,
"
writel(LCDIF_CTRL1_VSYNC_EDGE_IRQ, ®s->hw_lcdif_ctrl1_clr);
while (--timeout) {
