arch/z80/src/ez80/ez80f92_init.asm: Timer control register was not being cleared and, as a result, timer interrupts may have been already enabled when the CPU was started by the debugger. This would result in spurious interrupts and Unexpected Interrupt crashes. arch/z80/src/comming/up_initialize.c: Fix a trivial typo. While we are at it, change the license headers in all relevant files in the affected directories to the Apache 2.0 license. Run all affected files through nxstyle.
