KS8695: move TIMER_ definitions before code use

Move the TIMER_ definitions before they are used in KS8695 timer.c code.
Fixes:

timer.c: In function ‘timer_init’:
timer.c:37: error: ‘TIMER_COUNT’ undeclared (first use in this function)
timer.c:37: error: (Each undeclared identifier is reported only once
timer.c:37: error: for each function it appears in.)
timer.c:38: error: ‘TIMER_PULSE’ undeclared (first use in this function)
