linker_script: Remove some remaining SUBALIGN in iterable/linker sections

The zephyrproject-rtos#91219 missed some entries when doing the clean-up.
This removes some of remaining SUBALIGN entries in the iterable sections.
Fixes CMake Warning:
zephyr_linker_section(NAME ...) given unknown arguments: SUBALIGN 4
