The sw2iso count should cover ARM LDO ramp-up time,
the MAX ARM LDO ramp-up time may be up to more than
100us, this patch sets sw2iso to 0xf (~384us) which
is the default value.

For the slot support SD3.0 card, during system suspend, if plug out
the sd card, and insert another SD3.0 card, after system resume back,
SD3.0 card can't be recognised as SD3.0 card, just SD2.0 card.
This is bause the time delay between vmmc regulator off and on is
too small, this patch add the oo-on-delay in vmmc-supply regulator,
to assign proper delay value.

On imx_4.9.y we no longer override the cpu arm/soc/pu-supply properties
to link to pmic directly but rather rely on the regulator core
propagating a set_voltage on a bypassed regulator upwards.
This change was already performance for imx6qdl, now do it for all the
boards using ldo-bypass.

CMA region is a must to avoid the multile memory mapping
for the DMAed memory and also benifit the large continious
phisical memory allocation.
The default value is depend on the target system design and
user cases definition. This is not suitable to put this into
the soc.dtsi, thus we put it into the board DTS.
customer can override the value by changing cma size in DTS file.
Again, customer need set the CMA size correctly according to the
target system. The incorrectly CMA size can cause Linux kernel fail
to boot up.CMA disabled or CMA size set to zero is also not allowed.

On i.MX6UL, the VDD_ARM_IN and VDD_SOC_IN use the same power rail
VDD_ARM_SOC_IN. For imx6ul-14x14-lpddr2-arm2 board, default, we use
ldo-bypass mode and use the external PMIC regulator for cpufreq.so
on this board, should use the setpoint of ldo-bypass mode.

Add dts for mx6ul-14x14-lpddr2-arm2 board.
Basic function tested: SD1/EMMC2/ENET/UART1 is ok.
This patch takes mx6ul-14x14-ddr3-arm2.dts as a reference.
