Add "nol2x0" early param to avoid initialisation of the L2 controller
Some development platforms may have issues with this controller, so
allow easy disabling from the kernel command line. The patch also adds
a check for l2x0_disabled in the realview_pbx.c code to avoid setting
additional L2x0 registers.
