[PATCH] USB: OHCI relies less on NDP register
Some OHCI implementations have differences in the way the NDP register (in roothub_a) reports the number of ports present. This patch allows the platform specific code to optionally supply the number of ports. The driver just reads the value at init (if not supplied) instead of reading it every time its needed (except for an AMD756 bug workaround). It also sets the value correctly for the ARM pxa27x architecture.
