[PATCH master] ARM64: clocksource: drop too early error message

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Constructors are executed directly after relocations were applied.
But only after applying relocations is it safe to run arbitrary C code.

This causes an issue: If arm_arch_timer_init() fails and CONFIG_DEBUG_LL
is enabled, the hardcoded serial port will be used, which may hang the
system if serial setup has not happened yet.

Avoid this issue by skipping the error message.

I have declarative PBL entry point support in the works, which would side
step this issue anyway, so doing anything fancy here right now is not
worth the effort.
