Uwe Kleine-König 553cdc1a92 pwm: lpc18xx-sct: Initialize driver data and hardware before pwmchip_add() ...

[ Upstream commit 0401f24cd238ae200a23a13925f98de3d2c883b8 ]

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.
