mx2/mx3: debug-macro.S needs deprecated symbols This fixes: arch/arm/kernel/debug.S:147: Error: constant expression expected -- `ldrne r3,=(((UART1_BASE_ADDR)-AIPI_BASE_ADDR)+AIPI_BASE_ADDR_VIRT)' arch/arm/kernel/debug.S:163: Error: constant expression expected -- `ldrne r3,=(((UART1_BASE_ADDR)-AIPI_BASE_ADDR)+AIPI_BASE_ADDR_VIRT)' when compiling for mx2 with CONFIG_DEBUG_LL=y. A similar error exists on mx3 and is fixed by this commit, too. These were introduced by aae7019382896cf1075a93acc564e42601bc44a2.

ARM: 5910/1: ARM: Add tmp register for addruart and loadsp Otherwise more complicated uart configuration won't be possible. We can use r1 for tmp register for both head.S and debug.S. NOTE: This patch depends on another patch to add the the tmp register into all debug-macro.S files.
