refactor(soc): Deprecate usb pin mappings

Browse Source 
usb_pins.h and usb_periph.h/c lists mappings of USB DWC signals to GPIOs used
to connect to external FSLS PHYs. However, those signals can be routed to any
GPIOs via the GPIO matrix. Thus, these mapping are meaningless and have been
deprecated.

Note: These macros are deprecated. When connecting USB OTG to an external FSLS
PHY, the FSLS Serial Interface signals can be routed to any GPIO via the GPIO
matrix. Thus, these macros are meaningless.
Todo: Remove in IDF v6.0 (IDF-9029)
