Gregory Nutt 2c8d876ab8 eZ80F92: Eliminate Spurious Interrupts
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.
