pwm: lpc18xx-sct: Initialize driver data and hardware before pwmchip_add()
When a driver calls pwmchip_add() it has to be prepared to immediately
get its callbacks called. So move allocation of driver data and hardware
initialization before the call to pwmchip_add().
This fixes a potential NULL pointer exception and a race condition on
register writes.
