[ARM] 5136/1: pxa: fix PWM device order for pxa27x

Currently PWM0/2 (pxa27x_device_pwm0 at 0x40b00000 and 0x40b00010
are registered as as pwm_id 0 and 1, PWM1/3 (pxa27x_device_pwm1 at
0x40c00000 and 0x40c00010) are registered as pwm_id 2 and 3.
This patch corrects the pwm_ids to match the documented register names.
