The new LPC with USB mention that they have faster I/Os because they 
are connected directly to the processor bus!

If the peripheral bus frequency is same as the processor then how it 
is going to be faster?

Because the AHB bridge and AHB-to-VPB bridge add five clocks to each 
load and store, so that a load takes 8 clocks and a store 7 clocks.
Directly on the memory bus, a load takes 3 clocks and a store 2
clocks.
