This generalizes the in-kernel syscall approach from KERNEL mode to
all build modes so that to unify in-kernel syscall invocations. As
a result, machine mode ECALL and the supervisor folder are no longer
needed.

When executing fork() via a system call, the parent's stack gets corrupted
by the child, as during exception return the child loads the parent's
stack pointer from the context save area.
This happens because the full parent stack (including what has been pushed
during the system call) is copied to the child. What should be copied, is
only the user stack of the parent (the kernel stack is not interesting).
Fix this by only copying the parent's user stack to the child; and make
the child return directly to userspace (not via dispatch_syscall).
Simplifies the implementation of dispatch_syscall, making it easier to
understand and maintain. Let the C-compiler do most of the work, instead
of doing everything as inline assembly.
This adds the necessary defines to set the USARTs' kernel clock source
selection.
This is required for a configuration where the bootloader (running
before NuttX) changes the USARTs' clock selection, so they need to be
restored on board init.
This is according to the reference manual RM0399 page 448.

This revises PROTECTED build for qemu-rv mainly to avoid hard-coded
addresses in linker scripts. It also added rv32 support, cleaned up
config `pnsh64` and added config `pnsh`.

This adjusts sbi_start behavior so that if SBI late initialization hook
is defined, PMP setting is assumed to be fully done in the hook, because
the default PMP operation may fail for various reasons such as lacking
free entries or the default setting doesn't work on devices like QEMU
v6.2.

Other ESP32-S3 modules (with embedded flash and PSRAM) were added.
Also, the `help` section of the Kconfig was updated to better
describe the modules' flash and PSRAM sizes.
Steppoint can be implemented by icount(instruction count)
from RISC-V debug extension, but it may not implemented in all RISC-V cores.
Unfortunately, the currently supported RISC-V cores do not implement it.

Provide `up_copy_section` function that enables copying data using
the data bus. If the memory destination address is accessible
through the instruction bus, the data is copied using the
correspondent address accessible through the data bus.
rename _rdtsc macro to rdtsc to avoid conflict with external code
rename rdtsc macro to rdtscp to be the same as asm instruction used

The buffer initialization function (`i2s_buf_initialize`) calls
`i2s_buf_free`, which performs buffer initialization within a
critical section (`spin_lock_irqsave`). If this function is called
under the same critical section (same spinlock), initialization
will hang.
This change implements a driver for the two watchdog timers on the BL808, and enables it as part of the timer config. The driver is based on the GP timer driver.
