Subject: [PATCH v2] MIPS: Fix build with DEBUG_ZBOOT and MACH_JZ4770

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.
