(INIT_ENTRYPOINT): Document that the signature of "main" must take
"argc" and "argv" or else compilation error results, as discussed in
the email thread below [1].

NuttX generates the app main name from Kconfig symbol
xxxx_PROGNAME. The documentation was defining manually
the entry point as custom_hello(int char, char *argv[])
and pointing CONFIG_INIT_ENTRYPOINT="custom_hello".
The right thing to do is creating the application entry
point as "int main(int char, char *argv[])" and the build
system will add "_main" to the PROGNAME.

Correctly releasing channels after using QSPI is crucial
to prevent issues caused by multiple requests that may lead
to DMA channel resource conflicts.
The common `up_allocate_heap` is a strong symbol, which leads to
error when building with CONFIG_DEBUG_LINK_WHOLE_ARCHIVE. Make
`up_allocate_heap` weak function to mitigate this problem.

This PR configures the BL808 and SG2000 MMU (inside T-Head C906) to cache the the Kernel Text, Data and Heap. We set the MMU Flags (Shareable, Bufferable and Cacheable) as explained in this article: https://lupyuen.github.io/articles/plic3#appendix-mmu-caching-for-t-head-c906
This PR fixes the Slow Memory Access for NuttX Kernel in BL808 and SG2000: https://github.com/apache/nuttx/issues/12696
In the next PR, we will fix the Slow Memory Access for NuttX Apps, by caching the User Text and Data.

If run nsh over usb based serial port, the default stack size is too small,
for example simple `ps` command will use more than 2208 bytes stack.
Then the stack overflow will happen and the system will hang here.
