On the LS1028A the FlexSPI clock is connected to the first HWA output,
see Figure 7 "Clock subsystem block diagram".

On the LS1028A the ENETC reference clock is connected to 4th HWA output,
see Figure 7 "Clock subsystem block diagram".
The PHC may run with a wrong frequency. ptp_qoriq_auto_config() will read
the clock speed of the clock given in the device tree. It is likely that,
on the reference board this wasn't noticed because both clocks have the
same frequency. But this must not be always the case. Fix it.

While running 'make dtbs_install', the following error occurs:
make[3]: *** No rule to make target 'rootfs/freescale/imx8mm-kontron-n801x-s.dts', needed by '__dtbs_install'.
It should be .dtb, not .dts.

Different revision of i.MX8MP 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.MX8MP 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.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.
