User can pass arguments as part of write to requests and endpoint number
will be calculated based on the arguments. There is a chance that driver
can access ep structue that is not allocated due to invalid arguments
passed by user. Hence fix the issue by having check and return error in
case of invalid arguments.

Provide a hw guarantee that a userspace watchdog process receives cpu time.
Move ping_other_cpus() prior to waiting for the userspace signal in order
to minimize the effect of a late userspace pet on the safety margin. The
safety margin is the difference between the workqueue's timer interval and
the bite interval.

GSI EPs are assigned to the last 2 IN EPs. While allocating
the TX FIFO sizes we need to iterate over all IN EPs to correctly
allocate larger TX FIFOs for GSI accelerated endpoints.
Update the logic from using min_t(int, dwc->num_in_eps,
cdev->config->num_ineps_used + 1) to just use dwc->num_in_eps.
The EPs that are not enabled will be given the default TX FIFO
size while the ones that are enabled are given TX FIFO sizes
based on the burst size configured for that EP.
