Subject: [PATCH AUTOSEL 4.4 01/14] xtensa: fix build for cores with coprocessors

From: Max Filippov <jcmvbkbc@...il.com>

[ Upstream commit e3cacb73e626d885b8cf24103fed0ae26518e3c4 ]

Assembly entry/return abstraction change didn't add asmmacro.h include
statement to coprocessor.S, resulting in references to undefined macros
abi_entry and abi_ret on cores that define XTENSA_HAVE_COPROCESSORS.
Fix that by including asm/asmmacro.h from the coprocessor.S.
