f_domain is used to determine protocol family when CONFIG_NET_IPv4 and CONFIG_NET_IPv6 are both defined, but not correctly used in ipv4_dev_forward because of typo (there's not a config named CONFIG_NET_IPv5) which may cause IPv4 packets to be forwarded as IPv6.

This change moves the static vars to the appropriate place to follow the coding standard. It also adds comments as sections and `static` where necessary.

The default size in QEMU system is 128MB, and the size specified in chip.h is also 128MB. However, the region size for MMU was 512MB, so fixed it.

Summary:
- This commit refactors the entry point name for BUILD_KERNEL
to avoid misunderstanding the name
Impact:
- None
Testing:
- Tested with rv-virt:ksmp64

Summary:
- I noticed that the OS timer sometimes proceeds fast when
a task is scheduled to run on CPUO via IPI.
- Actually, qemu-rv implementation shares supervisor software
interrupt for both timer and IPI on CPU0.
- This commit fixes this issue.
Impact:
- qemu-rv only
Testing:
- Tested with qemu-6.2

Summary:
- This commit adds ksmp64 configuration to test BUILD_KERNEL+SMP
- NOTE: README.txt has been updated
Impact:
- None
Testing:
- Tested with QEMU 6.2

Summary:
- This commit adds SMP support for BUILD_KERNEL
Impact:
- RISC-V: BUILD_KERNEL + SMP only
Testing:
- Tested with rv-virt:ksmp64 (will be added later)

Run-time check for L3 page table size, to ensure it is large enough
to map all of the kernel memory.
NOTE: The check has to be run-time, as KFLASH_SIZE/KSRAM_SIZE are really
linker relocation symbols, and thus cannot be utilized compile-time.
L3 table maps 2MB of memory, this brings an implicit requirement for
any L3 region to be aligned to 2MB. This commit adds build time sanity
checks to ensure this requirement is met.
For other SvXX architectures the boundary requirement (might be) is
different.
Summary:
- I noticed that sometimes automatic tests failed due to
missing serial outputs, although the kernel is still alive.
- This commit fixes the issue.
Impact:
- raspberrypi-pico:smp only
Testing:
- Tested with smp, ostest, etc.

Summary:
- This commit introduces g_percpu_spin to avoid deadlock
in riscv_percpu.c instead of using the global spinlock.
Impact:
- None
Testing:
- Tested with rv-virt:knsh64 and rv-virt:ksmp64 (will be added later)

This allows properly using 10/100Mbps also with 1G phy. Some gigabit PHYs
come out of reset with 1G advertisement enabled, causing other devices to
set up link with 1G. If, after this, the link is set to 10/100 on the mpfs,
the link won't work.

Summary:
- In RISC-V, BUILD_KERNEL uses S-mode and to use M-mode timer
we need to handle it by using OpenSBI or self-implementation.
- This commit adds M-timer self-implementation for BUILD_KERNEL.
Impact:
- qemu-rv only
Testing:
- Tested with rv-virt:knsh64 on qemu-6.2

Summary:
- I found inappropriate SET_CSR() usage in the function.
