Subject: [PATCH 4.19 27/32] hexagon: define ioremap_uc

From: Nick Desaulniers <ndesaulniers@...gle.com>

commit 7312b70699252074d753c5005fc67266c547bbe3 upstream.

Similar to commit 38e45d81d14e ("sparc64: implement ioremap_uc") define
ioremap_uc for hexagon to avoid errors from
-Wimplicit-function-definition.
