usb: dwc3: gadget: fix dcache invalidate for event buffer

The second parameter of invalidate_dcache_range() is the end address
to invalidate up to not the invalidation length, so wrap a new API
dwc3_invalidate_cache() make the driver easy to use.

Move up the invalidation operation into event buffer check instead of
event buffer process to reduce the invoked times.

usb: dwc3: ensure consistent types for dwc3_flush_cache

The dwc3_flush_cache() call was declared and used inconsistently:
* The declaration assumed 'int' for addresses (a potential issue
when running in a LP64 memory model).
* The invocation cast the address to 'long'.

This change ensures that both the declaration and usage of this
function consistently uses 'uintptr_t' for correct behaviour even
when the allocated buffers (to be flushed) reside outside of the
lower 32bits of memory.
