[PATCH] ARM: dts: lpc32xx: set pwm1 & pwm2 default clock rate

[Sylvain Lemieux]

From: Sylvain Lemieux <slemieux at tycoint.com>

Probably most of NXP LPC32xx boards have 13MHz main oscillator
and therefore for HCLK PLL and ARM core clock rate default
hardware setting of 16 * 13MHz = 208MHz and the AHB bus clock
rate of 208MHz / 2 = 104MHz.

The change explicitly defines the peripheral PWM1/PWM2 default
clock output rate of 104MHz. If needed it can be redefined
in a board DTS file.

Note:
* There is a dependency on the following patch:
  "ARM: dts: lpc32xx: set default parent clock for pwm1 & pwm2"
  http://www.spinics.net/lists/arm-kernel/msg530277.html
* This patch should be apply after
  "ARM: dts: lpc32xx: add pwm-cells to base dts file"
  http://www.spinics.net/lists/arm-kernel/msg534050.html
  - There is no dependency between the patches.
