Subject: [PATCH] clocksource/drivers/exynos_mct: Fix section mismatch from the module conversion

The function register_current_timer_delay() when compiling on ARM32
fails with a section mismatch. That is resulting from the module
conversion where the function exynos4_clocksource_init() is called
from mct_init_dt(). This one had its __init annotation removed to for
the module loading.

Fix this by adding the __init_or_module annotation for the functions:
 - mct_init_dt()
 - mct_init_spi()
 - mct_init_dt()

Compiled on ARM32 + MODULES=no, ARM64 + MODULES=yes, ARM64 +
MODULES=no
