[PATCH v4 0/2] Static initcalls

This series replaces the dynamic initcalls (with function pointers) with
static calls, and gets rid of initcall_run_list(), init_sequence_f,
init_sequence_f_r and init_sequence_r. This makes the code simpler and the
binary slighlty smaller: -2281 bytes/-0.21 % with LTO enabled and -510
bytes/-0.05 % with LTO disabled (xilinx_zynqmp_kria_defconfig).

Execution time doesn't seem to change noticeably. There is no impact on
the SPL.

Changes in v4:
- Fold all changes to board_init_*() into a single patch
- Use '#if CONFIG_IS_ENABLED(FOO) INITCALL(init_foo) #endif' instead of
'CONFIG_IS_ENABLED(FOO, (INITCALL(init_foo);));' (Caleb C., Simon G.).
As a consequence, drop Michal's patch ("common: board: Simplify array
with function pointers with CONFIG_IS_ENABLED").
- Rebase on next

Changes in v3:
- Use printf() rather than debug() to report initcall failures
(Quentin S.)
- initcall_run_f(): replace one erroneous call to WATCHDOG_INIT() with
WATCHDOG_RESET() (Ilias A.)
- Fix relocate_code() in arch/sh/lib/board.c to address CI failures with
r2dplus (https://lists.denx.de/pipermail/u-boot/2025-January/576213.html)
(Tom R.)
- Add comments to initcall_run_f() and initcall_run_r() (Simon G.)

Changes in v2:
- INTICALL() and INITCALL_EVT() now call hang() immediately on error 
- Fixed typo: s/intcall_run_f_r/initcall_run_f_r/
