pwm: clps711x: Changing the compatibility string to match with the smallest supported chip
This patch changes the compatibility string to match with the smallest supported chip (EP7209). Since the DT-support for this CPU is not yet announced, this change is safe. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* Cirris Logic CLPS711X PWM controller
Required properties:
-- compatible: Shall contain "cirrus,clps711x-pwm".
+- compatible: Shall contain "cirrus,ep7209-pwm".
- reg: Physical base address and length of the controller's registers.
- clocks: phandle + clock specifier pair of the PWM reference clock.
- #pwm-cells: Should be 1. The cell specifies the index of the channel.
Example:
pwm: pwm@80000400 {
- compatible = "cirrus,ep7312-pwm",
- "cirrus,clps711x-pwm";
+ compatible = "cirrus,ep7312-pwm", "cirrus,ep7209-pwm";
reg = <0x80000400 0x4>;
clocks = <&clks 8>;
#pwm-cells = <1>;
