[PATCH] ARM: dts: bcm2837-rpi-3-b: fix pwm1 pin

[Baruch Siach]

Raspberry Pi 3 uses GPIO45 for I2C SCL0. pwm1 is on GPIO41. Update the
DT description accordingly. Fix the following error that shows when
GPIO44 and GPIO45 are configured to I2C:

[    1.751563] pinctrl-bcm2835 3f200000.gpio: pin gpio45 already requested by 3f205000.i2c; cannot claim for 3f20c000.pwm
[    1.762474] pinctrl-bcm2835 3f200000.gpio: pin-45 (3f20c000.pwm) status -22
[    1.775176] pinctrl-bcm2835 3f200000.gpio: could not request pin 45 (gpio45) from group gpio45  on device pinctrl-bcm2835
[    1.786344] bcm2835-pwm 3f20c000.pwm: Error applying setting, reverse things back
[    1.793980] bcm2835-pwm: probe of 3f20c000.pwm failed with error -22
