During Adafruit Bootloader compilation, I spotted bellow error which do not allow me build project.
``` c
inlined from 'hfclk_running' at lib/tinyusb/src/portable/nordic/nrf5x/dcd_nrf5x.c:785:13:
lib/tinyusb/src/portable/nordic/nrf5x/dcd_nrf5x.c:792:31: error: 'is_running' may be used uninitialized [-Werror=maybe-uninitialized]

```
Errata code referred to NRF_USBD_BASE.
This definition is not present in NRF5340 but both NRF52 and NRF53
do have NRF_USBD which maps to NRF_USBD_BASE for NRF52 and
to NRF_USBD_S_BASE for NRF5340.
This just make build possible for NRF5340.
NRF_USBD->SIZE.EPOUT[epnum] only need to write once to enable
Bulk/Interrupt transfer. We only need to do it in dcd_edpt_open() and
dcd_edpt_clear_stall()
ISO endpoints were not covered so far by the driver code.
This adds support for ISO IN and OUT endpoint handling.
Registers for ISO IN(OUT) endpoints are placed just after normal IN(OUT)
so in some cases common code could be used for handling all type of
transfers.
Generally code synchronizes ISO endpoint handling to SOF interrupt.
This code does not change the way of how non-ISO endpoints are treated.
Code uses strategy outlined in nRF52840 Produce Specification v1.0
sections 6.35.11.1 and 6.35.11.2.
Closing endpoints can be important when there are alternate
instances. This adds functionality of closing endpoints
similar to what exists in other drivers.
Operator < used in while condition was obviously incorrect.
Loop starts with checking if unsigned variable is less then 0.
This condition is always false.
This reverses condition to follow intention of of the code.
- replace tusb_hal_int_enable/disable to dcd_int_enable/disable,
hcd_int_enable/disable
- remove tusb_hal_init(), this will be part of dcd_init/hcd_init,
anything beyond dcd/hcd should be inited by bsp
