middleware: usb: update mcux usb host controller driver to support zephyr
 - add one porting file to use SDK usb host driver files in Zephyr - EHCI, KHCI, OHCI and IP3516HS driver include Zephyr USB port file if it is Zephyr environment - update hal_nxp.cmake to include controller drivers, phy driver and zephyr osa. - update patch list Signed-off-by: Mark Wang <[email protected]>

100100
- mcux-sdk/drivers/adc12/fsl_adc12.c: add guards to avoid compilation warnings when building
101101
with SDK clock control driver disabled.
102102
- Update the driver in mcux-sdk/drivers/cache/cache64/fsl_cache.c to use the non-secure flash address during cache invalidation.
103+
- Add usb_host_mcux_drv_port.h file for using MCUX SDK USB host controller driver easily in Zephyr.
104+
- usb_host_mcux_drv_port.h contains the simplified structs, enums and APIs that MCUX SDK USB host controller drivers need.
105+
- Update usb_host_ehci.c, usb_host_khci.c, usb_host_ohci.c and usb_host_ip3516hs.c if in Zephyr environment.
106+
- Add include of usb_host_mcux_drv_port.h.
107+
- Remove include of usb_host.h, usb_host_hci.h, usb_host_devices.h and usb_host_framework.h.
108+
- Update usb_host_ehci.c and usb_host_ip3516hs.c to not depend on usb_host_device_instance_t struct.
