Subject: [PATCH 4.16 004/272] MIPS: Fix build with DEBUG_ZBOOT and MACH_JZ4770

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Paul Cercueil <paul@...pouillou.net>

commit c60128ce97674fd05adb8b5ae79eb6745a03192e upstream.

The debug definitions were missing for MACH_JZ4770, resulting in a build
failure when DEBUG_ZBOOT was set.

Since the UART addresses are the same across all Ingenic SoCs, we just
use a #ifdef CONFIG_MACH_INGENIC instead of checking for individual
Ingenic SoCs.

Additionally, I added a #define for the UART0 address in-code and
dropped the <asm/mach-jz4740/base.h> include, for the reason that this
include file is slowly being phased out as the whole platform is being
moved to devicetree.
