leds: st1202: Set all pattern PWM slots to full after clearing pattern

pattern_clear() sets all PWM registers for the channel to LED_OFF (0).
In static mode (PATS=0), the LED output is ILED x Pattern0_PWM / 4095;
with Pattern0 at zero the LED remains dark regardless of the ILED value.

The LED1202 has a single global sequencer shared across all channels.
If another channel starts the sequencer after this one has been cleared,
the cleared channel runs through all 8 steps at zero duty cycle and
stays dark regardless of ILED.

Set all 8 PWM slots to ST1202_PATTERN_PWM_FULL so that ILED alone
controls the channel brightness in both static and sequencer modes.
