[U-Boot] [PATCH v1] rockchip: pwm: fix: pwm dosen't work on rk3288

According to rk3288 spec, the pwm register order is:
    PWM_PWM0_CNT,
    PWM_PWM0_PERIOD_HPR,
    PWM_PWM0_DUTY_LPR,
    PWM_PWM0_CTRL

but the source code's order is:
struct rk3288_pwm {
    u32 cnt;
    u32 duty_lpr;
    u32 period_hpr;
    u32 ctrl;
};

So, correct it here. It is the same as RK3399
