[RFC PATCH 7/7] arm: dts: pwm: replace polarity constant with macro

[Oleksandr Suvorov <oleksandr.suvorov@toradex.com>]

There is the PWM_POLARITY_NORMAL defined and describled in
<dt-bindings/pwm/pwm.h> and used by pwm drivers.

This patch converts all '0' constant in pwms parameters into
PWM_POLARITY_NORMAL.

Replace with sed regexp:
's/(pwms = <&[a-zA-Z_0-9]+ [0-9]+ [0-9]+) 0>/\1 PWM_POLARITY_NORMAL>/'

Then:
- included pwm.h in some dts/dtsi to fix building errors about undefined
  symbols.
- fixed the patman warnings about the code format;
