The keypad controller on NXP LPC32xx requires its clock gate to be open,
therefore add description of the requires 'clocks' property.

In addition adjust the example by adding description of required 'clocks'
property and by fixing 'interrupts' property.

if you find time, please review/ack this change before 5.0-rc5 to give
me a chance to push it through ARM tree, thank you in advance.

driver so we should acknowledge it.

can you please pull this documentation change through Linux input branch?

The two other dts changes have been already included into arm-soc.
