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

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

In SMP mode, if all cores start at same time, all from __start(),
then only primary need do initialize, so others core should wait
primary, use 'sev' let the non-primary continue to __cpuN_start().
