lpc32xx_pwm_config() is supposed to set duty_ns and period_ns,
it should not change PWM_ENABLE bit.

According to the LPC32x0 User Manual [1]:
For both PWM1 and PWM2 Control Registers:
BIT 31:
This bit gates the PWM_CLK signal and enables the external output pin
to the PWM_PIN_STATE logical level.
0 = PWM disabled. (Default)
1 = PWM enabled
So in lpc32xx_pwm_enable(), we should set PWM_ENABLE bit.
In lpc32xx_pwm_disable(), we should just clear PWM_ENABLE bit rather than
write 0 to the register which will also clear PWMx_RELOADV and PWMx_DUTY bits.

blocks found on Atmel AT91 SoCs. The VT8500 driver now supports changing
the PWM signal polarity and the TI drivers (EHRPWM and ECAP) gained
suspend and resume functionality.
User drivers can now query the core for whether access to a PWM device
will sleep (if the PWM chip is on a slow bus such as I2C or SPI).
The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK state
in addition to the FB layer's blanking states.
To round things off, a few fixes and cleanups are also included.

Correct operation for register writes is to perform a busy-wait
after writing the register. Currently the busy wait it performed
before, meaning subsequent register writes to bitfields may occur
before the previous field has been updated.

pwm_busy_wait() to use readl rather than readb.

This patch adds a PWM driver based on Atmel Timer Counter Block. The
Timer Counter Block is used in Waveform generator mode.
A Timer Counter Block provides up to 6 PWM devices grouped by 2:
* group 0 = PWM 0 and 1
* group 1 = PWM 2 and 3
* group 2 = PMW 4 and 5
PWM devices in a given group must be configured with the same period
value. If a PWM device in a group tries to change the period value and
the other device is already configured with a different value an error
will be returned.
This driver requires device tree support. The Timer Counter Block number
used to create a PWM chip is given by the tc-block field in an
"atmel,tcb-pwm" compatible node.
This patch was tested on kizbox board (at91sam9g20 SoC) with pwm-leds.
