[ Upstream commit 09f688f0718f57f9cf68ee1aa94490f641e759ba ]
The reg member of struct raspberrypi_pwm_prop is a little endian 32 bit quantity. Explicitly convert the (native endian) value to little endian on assignment as is already done in raspberrypi_pwm_set_property().
This fixes the following sparse warning:
drivers/pwm/pwm-raspberrypi-poe.c:69:24: warning: incorrect type in initializer (different base types) drivers/pwm/pwm-raspberrypi-poe.c:69:24: expected restricted __le32 [usertype] reg drivers/pwm/pwm-raspberrypi-poe.c:69:24: got unsigned int [usertype] reg
