Subject: [PATCH] pwm: raspberrypi-poe: Fix mailbox message initialization

architectures. So make sure we take that into account when populating
structures that are to be passed to RPi4's mailbox.

@arndb: This was just meged into the arm-soc tree some days ago. Should I
prepare a second PR once it's been reviewed?
