When NuttX is booted from a foreign (non NuttX)
bootloader. There as a possibility that the
bootloader configured the MPU, in an
incompatible way for the NuttX memory usage.
The option to reset the MPU before it is initialized
may not succeed if the bss and data initialization
code violated the previous MPU configurations.
Added herein are ARM_MPU_RESET and
ARM_MPU_EARLY_RESET. The former can be used
If the system is capable of booting and running
NuttX MPU configuration code without an MPU
violation. The latter is used if the system can
not run the bss and data initialization code.
These are options so that a NuttX may be configured to
not clobber a bootloader MPU configuration in a system
that is architected to share the MPU configuration task.
This commit adds header file imxrt_adc_etc.h for external ADC trigger
module. This contains only definitions of ADC_ETC registers and separate
bits, implementation of ADC_ETC driver is yet to be done.

If we repeatedly call up_cpu_pause and up_cpu_resume, there would be
cases where the next call to up_cpu_pause happens while the other CPU is
still responding to the previous resume request. In this case the
DEBUGASSERT will trigger. We should allow the first CPU to wait until the
other CPU has finished responding to the resume request.

The stm32_gpiosetevent calls stm32_configgpio. So
the pin is infact restored to the SDMMC/SDIO D0.
The seconday init, dropped interrupts in a debug
build with HW stack checking on after the GPIO glich
fixes and that was how it was detected.
This prevents gliches on changing to an output mode.
If not the ALT mux can be selecting a IP block that
is drving the line to say 0. Then the output is connected
to that source, then swithced to the correct source.

Rearchitect video driver:
- Define two video I/F(struct imgsensor_ops_s and struct imgdata_ops_s),
and support them.
- CISIF driver supports new video I/F struct imgdata_ops_s.
- ISX012 driver supports new video I/F struct imgsensor_ops_s.
- Move ISX012 driver to general driver directory.
Repeated automated sercon, serdis on VBUS proved to fail
for CDCACM DATA IN (device Serial TX). The root cause was
that the EP was left active after disconnect. This resulted
in the first serial write falling to kick-off the EP IN request.
That should restart the EP ISR.

This reverts commit 45672c269d.
Because:
* It's very confusing to have cc as LD.
* I don't see what "-nostartfiles -nodefaultlibs" in LDFLAGS are
supposed to do when we use LD directly. It would be simpler to
remove them from our LDFLAGS.

This is currently only used on STM32L4+ devices. Page erase in
flash_erase() function supports only dual-bank mode so it makes little
sense to configure this for unsupported single-bank mode.
