during migration from legacy pinout some of the FMC pins were ommited because
their names were identical to the new pinout, which didn't cause a compilation error.
This fixes LCD examples.
Also update incomplete stm32f769i-disco FMC support to avoid this kind of bug in the future
up_interrupt_context indicates that we self inside interrupt/handler mode,
replaced to private function is_nesting_interrupt to make less confused.

The case want to determine if a interrupt with higher priority and the
interrupt preemption occurred, but up_interrupt_context indicates that we
self inside interrupt/handler mode. As we previously did not handle the
ramvector interrupt correctly, after update breaked the case. We should
use a more clear private function is_nesting_interrupt.

Since the size of the shadow area will change during the script merging of global variables, it will lead to unpredictable number of links. After fixing, only three links are required.

1 On different architectures, we can utilize more optimized strategies
to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

Basic amg88xx sensor handling (open, close, read, ioctl).
No interrupts supported. I intend to add support for this feature when I
gain more know-how on nuttx/posix.
Make this_cpu is arch independent and up_cpu_index do that.
In AMP mode, up_cpu_index() may return the index of the physical core.

Some domains have a lot of IPv6 addresses. Because of that, it is
not possible to get the IPv4 address with getaddrinfo.
This change separate IPv4 and IPv6 cache size limit to enable to
get both IP addresses.
After the number of threads exceeds the array size, it will not be displayed.
Any number of threads can be displayed using dynamic adaptation

Prior to this commit, i2c and at24 may be used uninitialized on line
113, 117, 129, and 143 when gd32_at24_wr_test() is called the second
time because these two variables are not static. I don't think making
them static is the correct fix because i2c is released at the end of
this function. Fixed by removing the `if (!initialized)` condition
surrounding the initialization of i2c and at24, making them initialized
at every call to this function.

(1) Keep the `.init_array` and `.ctors` symbols and sort them according to their initialization priority.
(2) Exclude symbols ending with crtend.* and crtbegin.* to support c++
application.if we not exclude crtend.* crtbegin.* frame_dummy will be
added when enable any c++ application with global variables, this symbol
execution is problematic, removing it does not affect the application.
