db8500.dtsi: ab8500 at 5 reg property invalid length

[Stephen Warren]

Lee,

In commit 3de3d74 "ARM: ux500: Configure the PRCMU Timer for db8500
based devices in DT", you changed DT node prcmu at 80157000's #size-cells
from 0 to 1, but didn't adjust the reg property for existing sub-node
ab8500 at 5. Also, the indentation of the new subnode
prcmu-timer-4 at 80157450 looks wrong.

This makes dtc fail to compile snowball.dts:

Warning (reg_format): "reg" property in
/soc-u9500/prcmu at 80157000/ab8500 at 5 has invalid length (4 bytes)
(#address-cells == 1, #size-cells == 1)
