[PATCH 09/10] coresight: etm4x: replace __is_const_expr() by is_const()

[Vincent Mailhol via B4 Relay]

From: Vincent Mailhol <mailhol.vinc...@wanadoo.fr>

is_const() is a one to one replacement of __is_constexpr(). Do the
replacement so that __is_constexpr() can be removed.

Refer to [1] for an explaination of why __builtin_constant_p() can not
be used as a replacement here.

[1] commit 4d45bc82df66 ("coresight: etm4x: avoid build failure with unrolled 
loops")
