drivers: display_nrf_led_matrix: Correct calculation of pixel period
This is a follow-up to commit 4dfab40cac4c99eb28ef61dae0d5d1c062b5902f.
The calculation of the pixel period is done incorrectly and results
in higher than configured refresh frequency if pixels are refreshed
in groups. Fix that and lower the base frequency for the timer and
PWM so that wider range of refresh frequency can be used also with
the pixel grouping.
