[PATCH 4.14 082/343] ARM: dts: lpc32xx: add required clocks property to keypad device node

[ Upstream commit 3e88bc38b9f6fe4b69cecf81badd3c19fde97f97 ]

NXP LPC32xx keypad controller requires a clock property to be defined.

The change fixes the driver initialization problem:

lpc32xx_keys 40050000.key: failed to get clock
lpc32xx_keys: probe of 40050000.key failed with error -2

Fixes: 93898eb775e5 ("arm: dts: lpc32xx: add clock properties to device nodes")
