qspi and fspi host controller do not support read 1-4-4 mode. so need to
set the tx to 1, let the common code finally select read 1-1-4 mode.

On the i.MX8MM Beacon SOM, there is an RTC chip which is fed power

loaded, this can be a problem if the external RTC isn't rtc0.

rtc1 point to the SVNS in order to correctly hold date/time over
a power-cycle.

Different revision of i.MX8MM EVK boards may have different external
pull up registor design, some are enabled while some are NOT, to make
sure the WDOG_B pin works properly, better to enable internal pull up
resistor. Since enabling internal pull up resistor is NOT harmful and
having benefit of flexibility on different board design, just enable
it for all i.MX8MM boards; And schmitt input is NOT necessary for this
WDOG_B output pin, so remove it; Open drain outputs provide more
flexibility to a designer as they can be pulled-up to any voltage found
in the system, so enable it as well.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not

2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING

logical behavior behind the name "ACTIVE_xxx", this is:
