Q901 (IRLML6401) is p-channel MOSET, need set pin1 (LCD_nPWREN) to low
to let pin3 output be 3V3. Normally when pin1 is high, then pin3
output should be gated. It was working previously due to some leakage.
Correct the enable logic from the software viewpoint.

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.

We move WDOG_B pinctrl setting from pinctrl_hog to wdog driver, so need to
remove the original setting in pinctl_hog device node, otherwise the below
warning message will be caught:

The default gpio flag is 0 which actually means ACTIVE_HIGH.
However, it should be ACTIVE_LOW.
Change it using correct macro directly.
