[PATCH] arm64: s/CONFIG_AS_LSE/AS_HAVE_LSE/

[mark.rutland@arm.com (Mark Rutland)]

Michal objected to the use of the CONFIG_ prefix on definitions which
are not sourced from .config or Kconfig files, as these cannot be found
in the usual places.

Following the example of CC_HAVE_ASM_GOTO, replace CONFIG_AS_LSE with
AS_HAVE_LSE. This avoids confusion w.r.t. the CONFIG_* namespace, and
more accurately describes what the symbol represents.

There should be no functional change as a result of this patch.

This follows from Michal's reply [1] to a KCOV patch that followed the idiom
set by CONFIG_AS_LSE.

Mark.
