[PATCH] dm: core: allow DM_POST_INIT_F notification for TIMER_EARLY

[Chanho Park]

Since the Patch 55171aedda88, VisionFive2 booting has been broken [1].
VisionFive2 board requires to enable CONFIG_TIMER_EARLY but booting went
to panic from initr_dm_devices due to lack of a timer device.

- Error logs
initcall sequence 00000000fffd8d38 failed at call 00000000402185e4
(err=-19)

We can reproduce it on Qemu Sifive HiFive Unleashed emulation[2] after
enabling CONFIG_TIMER_EARLY manually.

Fixes: 55171aedda88 ("dm: Emit the arch_cpu_init_dm() even only before relocation")
