Commit 40686c394e53 ("riscv: Clean up IPI initialization code")
caused U-Boot failed to boot on SiFive HiFive Unleashed board.
The codes inside arch_cpu_init_dm() may call U-Boot timer APIs
before the call to riscv_init_ipi(). At that time the timer register
base (e.g.: the SiFive CLINT device in this case) is unknown yet.
It might be the name riscv_init_ipi() that misleads people to only
consider it is related to IPI, but in fact the timer capability is
provided by the same SiFive CLINT device that provides the IPI.
Timer capability is needed for both UP and SMP.
Considering that the original refactor does have benefits, that it
makes the IPI code more similar to U-Boot initialization idioms.
It also removes some quite ugly macros. Let's do the minimal revert
instead of a complete revert, plus a fixes to arch_cpu_init_dm() to
consider the SPL case.

Changes in v4:
- Include Sean's "Reviewed-by" tag
Changes in v3:
- Simply call riscv_init_ipi() in clint timer functions to avoid
some duplications
Changes in v2:
- Do the minimal partial revert instead of a complete revert, enough
to make HiFive Unleashed board boot again.

Since currently FU540 is broken, could you please adjust the patch
order to make this patch show up at the very beginning of the
u-boot-riscv/master tree?

Could we get this applied soon, since it's broken in u-boot/master?
